FAA enforcement actions
FAA enforcement records haven't been loaded into GroundCheck yet, so none can be shown — a gap in our data, not evidence of a clean enforcement history.
Maintenance disclosure history
Service Difficulty Reports are self-reported maintenance findings. The NUMBER of reports is not a measure of reliability — diligent operators file more, not fewer. These are shown for transparency, not as a negative signal.
3 reports on file.
DURING A SCHEDULED PILOT TRAINING FLIGHT THE GEAR WAS RETRACTED TO UP AND LOCK. A LOUD POP/BANG WAS HEARD AND THE NOSE LANDING GEAR (NLG) INDICATED NO UP AND LOCKED. HOWEVER THE MAIN LANDING GEAR (MLG) WAS UP AND LOCKED. THE MAIN GEAR SYSTEM WAS RECYCLED WITH SAME RESULTS. AIRCRAFT LANDED WITH MLG DOWN AND LOCKED AND NLG NOT DOWN AND LOCKED AFTER INSPECTION THE BELLCRANK IDLER WAS BROKEN. IT SUSPECTED THAT FATIGUE COULD BE THE CAUSE. INSPECTION OF SUSPECTED PART FOR CRACKS.
INSTALLATION PARTS ARE NOT COMPATIBLE. CESSNA AIR BOX SUPPORT 0555216-16 ATTACHES TO FORWARD ALTERNATOR BRACKET BOLT. THIS PREVENTS INSTALLATION OF LYCOMING LOCK PLATE 73383. APPARENTLY, THERE IS NO SB THAT RESOLVES THIS ISSUE. THIS PROBLEM RELATES TO REPORTS OF ALTERNATOR BRACKET FAILURES AND MAY CONTRIBUTE TO THIS PROBLEM. TYPICAL FIELD SOLUTION IS TO DRILL BOLTS FOR SAFETY WIRE INSTEAD OF USING LOCK PLATE. APPLIES TO ALL CESSNA 172 AIRCRAFT, SN 17263459 THROUGH 17267584, F172, SN F17201235 THROUGH F17201514.
CRANKCASE BREATHER TUBE MALFUNCTION. STOCK 172M BREATHER TUBE HAD SLIPPED DOWN IN CLAMPS. LOWER CLAMP COVERED 'WHISTLE HOLE'. THIS COULD RESULT IN BREATHER TUBE BLOCKAGE WITH ICE DURING FLIGHT AT LOW OUTSIDE AIR TEMPERATURE. SAME PROBLEM WAS ADDRESSED IN AD 82-07-02. (THIS AD WAS FOR MISSING WHISTLE HOLE IN STC APPROVED EQUIPMENT.) FIX WAS TO REPLACE BREATHER TUBE CLAMPS. PART TOTAL TIME: 18 YEARS, 6,000 HOURS.
