Definition
Small repair pieces of aircraft-grade fabric applied over minor tears, holes, or worn areas in the fabric covering of an aircraft, used to restore the integrity of the covered surface. Under FAA preventive maintenance rules, certificated pilots who own or operate an aircraft (not used in air carrier or commercial operations) may apply small simple fabric patches that do not require rib stitching or removal of structural parts or control surfaces.
Plain English
Patches of cloth glued or stitched onto the fabric skin of an aircraft to cover small tears or holes. Pilots are allowed to do this kind of small repair themselves on their own airplane.
Context Anchor
Seen in preventive maintenance lists for fabric-covered aircraft, especially when discussing small covering repairs an owner-pilot may be allowed to perform.
Derivation
Fabric originally means a material that has been made or woven. Patch means a piece used to mend a damaged area. In aviation, the words point to a repair piece made from approved aircraft covering material, not ordinary cloth.
Why Pilots Care
Lets a pilot or owner fix small fabric damage without taking the airplane to a shop, keeping it airworthy and reducing downtime.
Intuition Check
Do not think of a fabric patch as a casual cloth patch or tape stuck over a tear. In aircraft maintenance, it is a controlled repair using approved material and a proper process.
Example Sentence 1
Before the next flight, the owner applied two small fabric patches to cover the minor tears on the underside of the wing.
Example Sentence 2
Preventive maintenance allows fabric patches on non-structural areas as long as the repair does not require rib stitching or doping beyond the patch itself.
