Accident & incident history
Maintenance disclosures
ELT FAILED G-SWITCH TEST.
ON A ROUTINE INSPECTION, A MECHANIC FOUND THAT THE PILOTS RT RUDDER PEDAL PIN WAS ABOUT TO FALL OUT OF THE RUDDER PEDAL. FURTHER INSPECTION FOUND THAT THE ROLL PIN PN: NAS561C318 HAD FALLEN OUR OF ITS HOLE CAUSING THE RUDDER PEDAL PIN TO MIGRATE FROM ITS POSITION. INSPECTION OF RUDDER PEDAL ASSY FOUND THAT THE ROLL PIN HOLE IN THE RUDDER PEDAL HAD BECOME ENLARGED, DUE TO AN UNKNOWN REASON. RECOMMENDATION TO PREVENT RECURRENCE: ATTENTION TO ROLL PIN INSTALLATION FOR ADEQUATE PRESS FIT AND ADDITIONAL ATTENTION OF ROLL PIN ON ROUTINE INSPECTION. (K)
CRACKING OCCURRED IN A SHORT TIME SPAN, DURING NORMAL OPERATION. CRACKS WERE OVER AN AREA APPROX 7 INCHES X 7 INCHES. ONE PIECE APPROX 3 INCHES X 3 INCHES SEPARATED FROM THE PART. AFTER CRACKING, DEFORMATION OF LOWER TRAILING EDGE OCCURRED BECAUSE IT WAS NO LONGER RIGID. IF THIS PROBLEM HAD GONE UNNOTICED, HEAT DAMAGE WOULD PROBABLY HAVE OCCURRED TO ADJACENT PARTS. MATERIAL OR MFG PROCESS COULD BE SUSPECT. RECENT MFG BULLETIN CAB 07-2 AFFECTS SOME PRIMARY EXHAUST DUCTS DUE TO IMPROPER MFG, BUT IT DOES NOT APPLY TO THIS ONE. (MFG HAS BEEN MADE AWARE OF THIS PROBLEM, PART WAS RETURNED TO THEM ON REQUEST FOR EVALUATION). (K)
LT LONGERON 261310531 AND RT LONGERON 261310528 WERE FOUND CRACKED AT THE LOWER AFTER CORNERS OF THE CUT-OUTS FOR THE CONTROL COLUMN TORQUE TUBE. THESE CUT-OUTS ARE LOCATED JUST FORWARD OF THE NOSE GEAR SPRING SUPPORT FITTINGS 26430633. RT LONGERON HAS ONE CRACK .3750 INCH LONG AND A SECOND CRACK .7500 INCH LONG EXTENDING DOWN AND AFT TO THE NEAREST RIVET. LT LONGERON HAS ONE CRACK .7500 INCH LONG EXTENDING DOWN AND AFT TO THE NEAREST RIVET. PROBABLE CAUSE IS LOADS IMPOSED BY THE NOSE GEAR SPRING SUPPORTS AT A POINT WHERE THE LONGERON WEB HAS BEEN MOSTLY REMOVED TO CLEAR THE CONTROL COLUMN TORQUE TUBE. THIS DAMAGE CAN BE REPAIRED WITH A RIVETED DOUBLER OF HEAVIER MATERIAL.
FLASHING BEACON WIRE IN TAILCONE WAS ROUTED OVER THE BALLAST RESISTOR WHERE THERE IS LESS THAN .5 INCH CLEARANCE TO STRUCTURE. WIRE WAS NOT TOUCHING BALLAST RESISTOR OR AIRPLANE STRUCTURE, BUT INSULATION WAS BURNED CLEAR THROUGH TO BARE WIRE. WIRE SHOULD HAVE BEEN ROUTED UNDER AND AWAY FROM RESISTOR.
FLEXING OF MLG CENTER SPRING PN 2641014-3 CAUSES CENTER SPRING TO CONTACT MLG COVER PN 2611103-10 WHICH IS LOCATED BENEATH THE CENTER SPRING. CHAFING HAD WORN THROUGH THE PAINT ON THE LOWER SURFACE OF CENTER SPRING. TWO RIVETS HAD WORN INTO THE LOWER SURFACE OF THE CENTER SPRING. THESE RIVETS ARE THE CENTER IB RIVETS THAT FASTEN A FAIRING AT EACH END OF THE COVER. SUGGEST ELIMINATING THE CENTER RIVET AND INSTALL TWO RIVETS FURTHER OB AND OFF CENTER. ALSO APPLY CHAFE TAPE TO LOWER SURFACE OF CENTER SPRING.
WHILE CONDUCTING INITIAL INSPECTION, BOTH AFT WING TO FUSELAGE ATTACH BOLTS WERE FOUND SLIGHTLY RUSTED. DAMAGE WAS NEGLIGIBLE. THESE BOLTS AS WELL AS FORWARD ATTACH BOLTS AND UPPER AND LOWER STRUT ATTACH BOLTS WERE APPARENTLY INSTALLED DRY. THIS HARDWARE SHOULD ALL BE INSTALLED WITH A RUST INHIBITOR OR GREASE.
