CESSNA 402 C – ATA 2410 ALTERNATOR-GENERATOR DRIVE SYSTEM  – BEARING – FAILED. DR 611953878
LH Engine Alternator coupling (PN: 646655) bearing failure in flight. Engineers removed LH alternator and found crankshaft alternator drive gear (PN: 657984) had failed as well with subsequent metal contamination of the engine.
Engine, alternator and coupling will be sent to an approved overhaul facility for investigation and report.
CESSNA 402 C – ATA 3220 NOSE/TAIL LANDING GEAR – DRAG BRACE – CRACKED. DR 611953892
During scheduled NDT inspection, drag brace found cracked. Drag brace replaced.
AVIONS PIERRE ROBIN HR100 – ATA 2710 AILERON CONTROL SYSTEM  – CABLE – CORRODED. DR 611953900

CESSNA 402 C – ATA 5411 NACELLE/PYLON, FRAME/SPAR/RIB  – SPAR STRAP – CRACKED. DR 611953905
While carrying out cross beam replacement, cracks were found in the inner layer of both the inboard and outboard engine beam to Fwd spar straps.

Inboard beam has a single crack approximately 7mm in length extending from the relief cut out.  The intermediate layer behind it appears unaffected.

Outboard beam has 2 cracks approximately 5 and 10mm emanating from the inboard relief cut out and 2 cracks 5mm and 10mm emanating from the outboard relief cut out.  The intermediate layer behind this also appears to be damaged.

As this is an EO installation the design approval holder has been contacted for advice.

CESSNA 210 M – ATA 5511 HORIZONTAL STABILIZER, SPAR/RIB  – SPAR – CRACKED. DR 611953906
Whilst performing an inspection of the Horizontal Stabiliser Fwd Spar IAW AD/C210/069 Amdt 2, engineers observed two cracks on the rear face of the FWD horizontal stabiliser spar.

Both cracks are in the rear laminate and originate from the Centre section cut out.
1) lower crack measuring approx 14 mm in length and travelling toward the Right
2) upper crack toward the Left and measuring 11 mm.
The horizontal stabiliser has been removed from the aircraft for further assessment of the cracking, for either P21 repair or replacement.

CESSNA 210 L – ATA 5711 WING SPAR – SPAR – CORRODED. DR 611953920
Corrosion evident on lower surface of carry thru spar Assy. Suggested cause is the adhesive that is used to attach the foam strip to the lower surface absorbing moisture. Investigation to be carried out IAW Cessna SEL 57-06.
