12. MAINTENANCE
12.1. GENERAL
Apart from the consequences of heavy landing, or of exceeding flight limitations, the major factors for attention
are corrosion, fatigue and UV light. There is no inherent fatigue problem with the P&M Quik-GTR, but excessive
loads and vibration can weaken the structure, and a regular watch for hair-line cracks, most likely in areas under
high stress, such as around bolt holes, should be carried out. All components can be replaced without difficulty.
Repairs should be undertaken by a P&M Aviation Ltd. approved repair agency.
Aluminium Tubework
Care and consideration in de-rigging and transportation will pay huge dividends in airframe life. Any damage to
any one of the structural members is serious and can usually only be repaired by replacement. Tubes suffer
from abrasion or indentation, the first accelerating fatigue fracture and the second reducing the strength of the
part. If you bend, dent or damage the tubular members in any way, seek immediate professional advice before
flying again and have replacement parts fitted. All tubes are intended to be straight when unloaded, with the
exceptions of the pylon, seat frame, inner washout rod and top surface battens. See inspection schedule 12.5.
Fasteners
Only fasteners purchased from P&M Aviation Ltd either direct or through an Approved Stockist should be used
for replacement. Any fastener which is bent or shows sign of wear or corrosion should be immediately replaced.
Rigging Cables
The main danger with the rigging lies in kinking the cable, usually caused by careless rigging and de-rigging.
Once a cable has a kink, the strands are damaged and replacement is the only cure. Check for cable damage
along the length but the main failure area lies immediately adjacent to the swaged fitting. Look carefully for signs
of strand fracture at this position. Corrosion is a serious problem particularly in coastal areas and shows itself as
a white powdery deposit. Corrosion cannot be cured and replacement is the only answer.
Fittings
Many fittings on P&M aircraft are manufactured from aluminium alloy and then anodised. Damage can occur
through scratching or by the stress of an unduly heavy landing or crash, or by general wear. Look for elongated
holes, scoring and stress lines in the aluminium. Damaged items should be replaced.
Nyloc nuts should only be used once. Re-using
worn nyloc nuts could cause structural failure,
injury or death.
Kinked, corroded or damaged cables should be
changed at once with new factory supplied
items. Flying with damaged cables could cause
structural failure, resulting in injury or death.
Never fly an aircraft with dented or damaged
components.
