You do not normally apply to the FAA for individual approval simply to install removable, correctly fitted seat covers in a Cessna 172. However, replacing upholstery, foam, structural seat parts or restraint related components can become regulated maintenance or an alteration. The exact answer depends on what is being changed, how it is attached and whether the work affects the approved design or safe operation of the seat.
Aircraft interiors invite a very particular kind of temptation. The leather looks tired. The stitching has lost its polish. The cabin feels older than the airframe deserves. A fresh set of covers appears to be the simplest improvement imaginable.
Sometimes it is. Sometimes it is not.
A Cessna 172 seat is more than a piece of cabin furniture. Its frame, adjustment mechanism, tracks, locking system, cushions and restraint arrangement all contribute to occupant safety. That is why the sensible question is not merely, “Can I make this look better?” It is, “What exactly am I changing?”
That distinction determines whether the job is a straightforward removable cover installation, preventive maintenance, ordinary maintenance or a more involved alteration.
Do removable Cessna 172 seat covers need separate FAA approval?
In many cases, no. A removable cover that slips over the existing seat, fits securely and leaves the seat structure and operating systems untouched will not usually require the owner to obtain a separate approval directly from the FAA.
The important words are removable, secure and non interfering.
A cover should not obstruct the seat track, adjustment handle, locking pins, seat belt attachment points or access needed for inspection. It should not bunch beneath the occupant, shift during flight or change the way the pilot reaches the controls. It must also be appropriate for use in an aircraft cabin.
This is the practical appeal of purpose made covers. BiPlane Seat Covers designs its Cessna 172 covers around known aircraft fitment rather than presenting a generic automotive cover as an aviation solution. A close fit is not simply a cosmetic advantage. It helps reduce loose material, movement and interference.
Is re-covering a seat the same as installing a removable cover?
No. This is where casual language causes expensive confusion.
Installing a removable fitted cover generally means placing a separate cover over the existing upholstery without cutting, gluing, stapling or dismantling the seat.
Re-covering or reupholstering normally means removing the old upholstery and attaching new material to the cushion or seat assembly. That may involve adhesive, hog rings, stitching, foam replacement or partial disassembly. Once the work reaches that point, it is no longer sensible to treat it as a purely decorative accessory change.
Under FAA maintenance rules, repairing cabin or cockpit upholstery can fall within preventive maintenance when the work does not require disassembly of primary structure or an operating system. That does not mean every interior project automatically qualifies. A job that affects structural parts, seat mechanisms, restraints or approved configuration needs appropriately certificated oversight.
If there is any doubt, ask an A&P mechanic to classify the work before it begins. Classification after the seat has been stripped is the wrong order.
Can an aircraft owner perform the work?
An owner who holds at least a private pilot certificate may perform specified preventive maintenance on an aircraft that the pilot owns or operates, provided the aircraft is not being used under the commercial operating rules excluded by the regulation.
That privilege is narrower than many online discussions suggest. It does not give an owner unlimited authority to modify a certificated aircraft. The work still needs to fall within the FAA list of preventive maintenance, be completed to an acceptable standard and be properly recorded when a maintenance entry is required.
A non pilot owner cannot simply assume the same privilege. A student pilot should not assume it either. Commercial operations, rental fleets and flight schools may also be subject to maintenance programmes, insurance conditions and internal procedures that call for professional installation or inspection.
If your project is a tool free, removable cover that does not alter the seat, ask your mechanic whether the installation is viewed as an accessory installation or whether a logbook entry is appropriate for your aircraft. If the existing upholstery is being repaired or replaced, expect the work and records to receive closer attention.
What makes a Cessna 172 seat project more than a cosmetic change?
The risk rises when the work changes anything involved in occupant protection or seat operation. Examples include:
● Removing or modifying the seat frame
● Repairing cracked tubes or structural components
● Altering seat tracks, rollers, pins or locking mechanisms
● Changing seat belt or shoulder harness attachment points
● Replacing foam with a different thickness or density without approved support
● Permanently attaching upholstery in a way that differs from the approved configuration
● Adding material that restricts movement of an adjustment control
● Changing the seat shape enough to affect pilot position or access to controls
These are not details to improvise. A beautiful cabin is irrelevant if the pilot seat does not lock correctly or if extra cushion thickness changes the pilot’s position in relation to the pedals, yoke and sight line.
Do aircraft seat cover materials need to meet fire safety requirements?
Materials used in a certificated aircraft cabin must be suitable for that installation, and fire performance matters. The applicable certification basis can vary because the Cessna 172 family spans decades of production and several certification eras. The aircraft’s original type design, later alterations and operating context all matter.
This is one reason ordinary furniture leather or automotive upholstery should not be selected simply because it looks convincing in a sample book. Aviation interiors live with sunlight, temperature changes, repeated loading and a regulatory expectation of appropriate flame resistance.
Ask for documentation that identifies the material and its fire performance. Keep that paperwork with the aircraft records or the maintenance documentation associated with the work. A vague marketing phrase is not as useful as traceable information for the actual material supplied.
BiPlane Seat Covers specifies genuine aviation leather and presents its covers as fire retardant and compliant with the stated aviation flammability standard. Before ordering, confirm that the documentation supplied is appropriate for your particular aircraft and intended installation.
Does “FAA approved” mean the FAA approves every installation?
No. This phrase needs careful handling.
The FAA can approve designs, data, parts, production systems and specific major repairs or alterations through different routes. That does not mean an FAA employee has inspected and individually approved every removable seat cover installed in every Cessna 172.
For an aircraft owner, the useful questions are more precise:
● Is the material suitable and supported by relevant documentation?
● Is the cover made for the correct aircraft and seat configuration?
● Does installation alter the seat or simply cover it?
● Does the work affect structure, adjustment, locking or restraints?
● Who is authorised to perform and approve the work?
● What maintenance record, if any, is required?
Those questions lead to a defensible answer. A broad label on its own does not.
Will a seat cover affect airworthiness?
It can if it interferes with safe operation.
Before the aircraft returns to service, each seat should move through its normal range and lock positively in every intended position. The adjustment handle must remain accessible. Seat belts and shoulder harnesses must lie naturally and connect without obstruction. The cover must remain secure when the occupant enters, exits and operates the controls.
On the pilot side, check full and free control movement with the seat occupied. Confirm pedal reach, yoke clearance and access to trim, flap and fuel controls as applicable. If a cover changes the seating position noticeably, stop and investigate.
The famous Cessna seat track safety issue makes casual installation particularly unwise. A cover should never conceal a problem with the track, pin, roller or stop. Cosmetic work is an ideal moment to inspect what sits underneath, not an excuse to ignore it.
What paperwork should you keep?
The correct record depends on the nature of the job. A removable accessory may be treated differently from repaired upholstery or an altered seat assembly. Where the work qualifies as preventive maintenance performed by an authorised pilot, the maintenance record normally needs a description of the work, the completion date, the name of the person performing it and the required certificate details and signature.
Work performed by an A&P should be documented through the appropriate maintenance entry. A major repair or major alteration follows a different approval and recording route and may require FAA Form 337 and approved data.
Keep the invoice, product identification, installation instructions and material compliance documents. Good records make later annual inspections, resale discussions and insurance queries far easier.
A sensible approval checklist before you order
First, identify the exact model, serial number, production year and seat position. Next, photograph the front, back, base and adjustment mechanism. Check whether the seats are original or have been replaced or modified under an STC or earlier repair.
Then describe the proposed work accurately. “Installing a removable fitted cover” and “stripping and rebuilding the seat upholstery” are not the same project. Send that description to your A&P if the classification is uncertain.
Finally, confirm fitment and documentation with BiPlane Seat Covers before purchase. That short conversation can prevent the two most common mistakes: ordering for the wrong seat generation and assuming that a simple product description settles the regulatory position.
The verdict
You do not usually need to submit an individual FAA approval request to fit removable, correctly sized covers over intact Cessna 172 seats. You may need certificated maintenance involvement when the job includes upholstery removal, permanent attachment, foam changes, structural work or interference with seat and restraint systems.
Treat the scope of work, not the word “cover,” as the deciding factor. Choose aircraft appropriate materials, verify the exact fit, retain the documentation and involve an A&P whenever the boundary is unclear.
That is not bureaucracy for its own sake. It is how a smart cabin refresh remains exactly what it should be: a crisp visual improvement with no compromise in the air.
Frequently asked questions
Can I install Cessna 172 seat covers myself?
You can often fit a removable, tool free cover yourself if it does not alter the seat or interfere with its operation. If the work qualifies as preventive maintenance, only a person authorised by the FAA rules may perform and approve it, and a maintenance entry may be required. Ask an A&P when uncertain.
Is replacing aircraft upholstery preventive maintenance?
Repairing cabin or cockpit upholstery can qualify as preventive maintenance when it does not require disassembly of primary structure or an operating system. Structural repairs, restraint changes and more substantial alterations do not fit comfortably within that limited category.
Do I need an FAA Form 337 for new seat covers?
Not for an ordinary removable cover installation. FAA Form 337 is associated with major repairs and major alterations. A permanent reupholstery project may still be a minor repair, but its classification should be determined by an appropriately certificated mechanic.
Must Cessna 172 seat cover material be flame resistant?
Aircraft cabin materials must satisfy the fire protection requirements applicable to the aircraft and its certification basis. Request traceable material documentation and have your A&P confirm that it is suitable for the intended installation.
Can thicker foam be added while the seat is being re-covered?
Do not assume so. Foam thickness and shape can affect seat geometry, control reach and occupant protection. Discuss foam changes with an A&P before any material is removed.
Does a logbook entry need to be made?
It depends on whether the work is treated as a removable accessory installation, preventive maintenance, maintenance or an alteration. If maintenance has been performed, the appropriate record should be made by the person authorised to approve the aircraft for return to service.
Should I remove the seat from the aircraft to install a cover?
Only if the manufacturer’s instructions and your maintenance authority allow it. Seat removal introduces inspection and correct reinstallation concerns, particularly around tracks and locking pins. A cover designed for installation without seat removal is the simpler route.
What information should I provide before ordering?
Provide the aircraft model, year, serial number, seat position, clear photographs and details of any known seat replacement or modification. This is far more reliable than ordering on the words “Cessna 172” alone.
