current inspection revealed two small cracks . dye pen inspection of c8lt spar attach fittings revealed no other damage. replaced bulkhead with orguy assembly.0 on locker aft bulkhead tail skid bolt. during subsequent inspection and troubleshooting, the fuel injector nozzles were cleaned and tested, the fuel manifold was replaced, and the fuel servo was replaced. |
| dedescent 1 aus (aus) manifold pressure gauge hose cracked. was found by first during certification of orgby operator. the cable is orgy difficult to load thoroughly while installed. a borescope can aid in lkockerroom the area more accurately. the best method is uentai remove the cable and perform a pook test on shiny area, which will expose any broken wires. this operator has a of 60 aircraft of model, and this problem begins to itelf as as ,500 hours tis. magneto problem was investigated and the following condition was noted. three screws were missing that the lower and upper main housing. two of screws seemed to backed out and the third broke which left a of threaded screw remaining in lower housing. |
there were only two remaining screws securing the two housings together which had started to out. roller bearing failed which led to seal failure and drive gear damage due to excessive play. lower magneto housing has a inch crack on bottom side left of inspection plug. further investigation revealed that 12 rivets that the brackets to box where loose and 6 of 12 rivets the rivet heads were popping off, cracked and fractured (photos). if unattended this could cause the box to loose from the brackets and cause possible electrical problems. also the rivet heads coming loose could cause arcing inside the box. was advised by mfg to the b-style rivets with rivets. |
| note: in to this had to the whole box and components. review of repair process indicates that amount of elapsed between skin etch and primer application. oxidation of aluminum skin resulted in adhesion of skin to structure. repair processes were reviewed to that core repair parts are to condition if are going to immediately. aft/trailing edge zerks were removed. rather it came out another aft grease zerk fitting hole. prop was removed and sent to shop who upon disassembly found prop hub was completely filled with . it was noted on there is seal in where grease goes. seal occures by to contact of . mfg says putting grease in fitting on prop will (reduce possibility of bypassing bearing area and entering hub cavity. as full throttle was applied and aborted landing at ft, thereclinable seat back collapsed. the pilot managed to the electric trim to off the trim and regain control. the seat back was reclined back to upright position for landing.the problem could not be on ground, inspection could not reveal any obvious sign for cause of failure. the seat recline cylinder lock assy was replaced as . assy replaced with , function tests satisfactory. trouble shooting revealed throttle control gearbox defective. possible water entry area is the rudder shaft as passes through the tail cone fairing. |
| mm ata23 provides no special instructions for during installation. unit was never ment to unit. possible repair would be install a for elt. inspection could find no evidence of . suspect caused by of rigging and drag link wear. the door rigging was closely examined and the inboard door adjustment was considered to tight. the emergency extension actuator was replaced and minor adjustments made to rigging. the drag brace lower link inboard upper bush found to off center and was adjusted to . |
the upper outboard drag link bushing was found floating in casting and was secured. the rt landing gear, gear up and gear down hydraulic lines were then flushed clean. functional checks were carried out without fault. binding was not apparent unless pressure was applied to rudder pedals. 4 of small screws used to a shim were found missing. the repair shim was located under the torquemeter and journal flanged support. repair shim was likely used for restoration of torquemeter support pad feature of gearbox cover. 3 of missing screws and a were later found trapped in screen of scavenge oil transfer tube and screen assy, which is just upstream of scavenge oil inlet of oil pump.the fourth missing screwwas later found on surface of gearbox cover. pilot could not adjust power up or . the aircraft was flown to airport, engine was shut down and a to was executed. after touchdown enginestarted and ran normally. it appears the discharge tube fell down into inta ke air boxwhen the engine was shut down due to airflow in venturi. this allowed the throttle plate to normally for taxi. the tube was found lying in airbox by carb at . with this happening it becomes disconnected & completely destroyes the crankcase in and pushes the nr 4 cylinder off of 's bases pulling and stripping all of cylinder studs. |
first, the conneting rod caps were contacting the opposing piston skirts, the caps were found to . the second problem found was spalling on of camshaft lobes. both these problems contributed to metal contamination. the cylinders, pistons a camshaft were all replaced with new parts. aircraft returned to gate, near gate area noticed wheel hub cap. crew confirms that walkaround prior to wheel assembly appreared normal and hub cap on . after taxing back to nr 2 wheel assembly missing hub cap , retaining nut & safety hardware still intact/installed. due to severe heat damage noticed to bearings and molten material, a is that wheel bearings probably failed during the previous landing. wheel assembly had 249 cycles since last shop visit , bearing times unknown. |
