Propeller Strike Inspection

Sl. No.	Items	Mech	AME
1.	Consult the pilot as to the nature of the propeller strike incident.
2.	Inspect the propeller for damage
3.	Check the tightness of the propeller attachment bolts.
4.	Remove the propeller.
5.	Mount a D.T.I. and check the propeller flange run out.
6.	Inspect the back side of the flange at the radius to the shaft for any cracks.
7.	Inspect the crankcase visually for any cracks.
8.	Inspect the engine attachment to the engine mount for any damage.
9.	If there is a sudden stoppage of engine due to propeller strike, engine should be removed from the aircraft and sent to an approved overhaul facility for disassembly and detailed inspection.
10	Carryout any other inspections suggested by Manufactures.

Heavy Landing

Sl. No.	Items	Mech	AME
1.	Remove all inspection covers, fairings, floorboards and cowlings to facilitate inspection.
2.	Check for wrinkling of aircraft skin particularly in the main landing gear attachment area and nose gear attachment area.
3.	Check main landing gear spring strut for evidence of damage, distortion, crack and general condition.
4.	Check main landing gear fuselage attachment for damage, security and fuselage bulkheads for evidence of distrtion and crack.
5.	Remove main wheels and inspect wheel assy. for condition and damage.
6.	Check main wheels axle assy. for damage and security.
7.	Check nose gear attachment to fuselage for damage, distortion and security.
8.	Check nose gear / Oleo for evidence of fluid leak and extension. If necessary reservice the nose strut.
9.	Remove nose wheel and inspect wheel assy. for condition, cracks and damages.
10.	Magnaflux nose wheel axle.
11.	Check nose wheel shimmy dampner for damage and security.
12.	Check nose gear torque links for damage and security.
13.	Examine wing strut for bowing. If struts are found bowed, as certain cause and check strut attachment fittings at fuselage location and wing location for damage.
14.	Magnaflux strut attachment bolts.
Sl. No.	Items	Mech	AME
15.	Check wing attachment fittings to fuselage for damage.
16.	Check horizontal stabilizer attachment for signs of damage.
17.	Check vertical stabilizer attachment for signs of damage.
18.	Check flying control cables for slackness and layout.
19.	Check all instruments for proper functioning.
20.	Inspect the engine attachment to engine mount for any damage.
21. i). ii). iii).	If the wing tip grazes the ground, in addition to the above, carry out the following: Check incidence and dihedral of mainplane and tailplane. Check also symmetry of aircraft. (if any change, establish cause). Check wing tip bow structure for distortion / damage. Check for damage / distortion of wing spar structure internally upto and around the wing strut attachment point.
22.	Ground run engine and check performance of engine and instruments.
23.	Carry out taxy test.
24.	Check swing magnetic compass.
25.	Check the external condition of radio (by AME(R) or AME and the function should be certified by AME(R) or pilot training instructor).
26.	Test fly the aircraft, if required after pre – flight inspection.

Turbulent weather inspection

INSPECTION PROCEDURE WHEN AIRCRAFT HAS PASSED

THROUGH TURBULENT WEATHER   

Sl. No.	Items	Mech	AME
1.	Consult the pilot regarding details of aircraft rough flying and whether any noise indicative of structural failure was heard.
2.	Carry out symmetry check on the aircraft.
3.	Check externally the fuselage, main planes, tail planes and the control surfaces for any signs of damage and wrinkles in the skin.
4.	Check windshield for any cracks.
5.	Check for any signs of fuel leak and seep from the fuel tanks.
6.	Check fuselage and engine mount for any distortion and damage.
7.	Inspect main plane attachment, tail plane attachment, under – carriage attachment and engine mount attachments for any signs of distortion and damage.
8.	Inspect wing strur for Bowing.
9.	Examine control surface hinges for evidence of damage.
10.	Check flying controls for full, neutral position and free movement (Record control movement).
11.	Check all instruments and instrument panel for damage and security.
12.	Check fit of doors and surroundings area for distortion.
13.	Check engine cowling for wrinkles and distortion.
