Pos. 1: Inspect nose gear leg for cracks and deformation especially between the fitting (aluminum) for connection of nose
gear-leg to fuselage.
Pos. 2: Inspect aluminum fittings for connection of nose gear-leg to fuselage, Teflon-insert in aluminum fitting and
surrounding structure, for cracks and deformation.
Pos. 3: Inspect nose gear in the unloaded state, especially nose gear fork, tire radial run out, bearings and nose gear
linkage. Check for cracks, deformation and increased play. See
Nose Gear FK9 TM-FK9/FK14#01-2009
.
Pos. 4: Inspect complete nose gear to pedals linkage in the unloaded state, especially the bell cranks. Check for cracks,
deformation and increased play. See
Nose wheel steer play
.
Pos. 5: Check nose wheel shock-absorber and spring, for cracks, deformation or leakage.
Pos. 6: Check nose wheel-strut to engine for cracks or deformation.
Pos. 7: Check suspension point from nose wheel-strut to engine mount for cracks.
Inspect complete main gear assembly (for cracks, deformation and play).
Pos. 1: Inspect main gear spring for cracks deformation and position.
Note:
Be aware that the composite main gear spring can collapse, due to their characteristics, long after the overload
Pos. 2 : Check if washer plates for main gear spring is in position.
Pos. 3: Inspect main gear spring attachment points and surrounding structure for cracks.
Pos. 4: Check if main gear spring screw M8x35 10.9 DIN 933 shows cracks or fracture.
Pos. 5: Inspect complete main wheel assembly, especially tire radial run out, bearings, main gear wheel axle and brake
system. Check for, cracks, deformation, increased play and leakage.
In addition to mentioned inspections, carry out an inspection of the complete engine mount frame, engine shock mounts
and engine mount frame attachment points on the firewall.
Furthermore, check the attachment points of the wings, wing struts and stabilizers to the fuselage for cracks, play and
deformation.
