DR 611851568 AIRBUS A321 231–ATA 2760 DRAG CONTROL SYSTEM–SPOILER–Dispatched in Maintenance Mode. During flight, F/CTL SPLT fault on ECAM was presented. No.1 spoiler was deployed on the LHS wing. Reset unsuccessful. During ground inspection, spoiler was found in maintenance mode. Spoiler was re-activated per the AMM procedures. Subsequent tests including independent inspection found nil further issues.

DR 611851504 CESSNA 210 N–ATA 5511 HORIZONTAL STABILISER, SPAR/RIB–SPAR–CRACKED. Horizontal stabiliser FWD spar found cracked. Crack is at the lower LH radius of the centre cut out. The spar is a three-layer construction with only the middle layer cracked. The crack is very fine and only has a total length of 0.125″. Repaired I.A.W. approved EO. i.e. stop drill and doubler repair.

DR 611851615 CESSNA U206 G–ATA 2750 TRAILING EDGE FLAP CONTROL SYSTEM–Sync Rod–BROKEN. Aircraft required significant right aileron input to remain straight and level. Flaps retracted in stages and flight diverted to alternate for flapless straight on approach. On landing with flap selector set to 0 degrees, flaps extended towards 20 degrees during rollout. During ground inspections, RH flap sync tube assembly was found to be failed. Rectifications and investigation is continuing.

DR 611851627 PIPER PA25 235–ATA 2720 RUDDER CONTROL SYSTEM–CABLE–DAMAGED. Damaged rudder cables were noticed after removing turtle deck. Preliminary examination indicated that cables may have been lubricated where they ran through the plastic guide bushes down to the rear sides of the fuselage. Cables were covered in dust which had adhered to the lubricated cables, forming a grinding paste. Maintenance organisation has been notified. RH rudder cable had approx. 60% of the wire strands broken. Whereas LH cable was similarly damaged with approx. 40% of wire strands broken.

DR 611851600 HAMILTON STANDARD 14RF-19–ATA 6114 PROPELLER HUB SECTION–Bearing Race–DAMAGED. During a routine maintenance task, it was found that bearing races were damaged on two blades of the LH propeller. OEM contacted. This is currently a known defect under investigation. Both propeller blades were replaced, with the hub and the actuator due to metal contamination.

DR 611851499 ATA 2561 LIFE JACKET–BATTERY PACK–Swollen–PART NO. WAB-H18 P/N 517-09. Total of 9 x WAB-H18 orange batteries found swollen during scheduled maintenance. Possible reason could be manufacturing defect at the composition level of the batteries and or moisture/humidity. Defective EAM WAB-H18’s P/N 517-09 light/battery assemblies have been found to be unreliable for many years. OEM has been provided a report.

DR 611851474 PRATT AND WHITNEY PT6T 3DF–ATA 7261 TURBINE ENGINE OIL SYSTEM–CHIP DETECTOR–Chip detector light ON. After departure, #2 engine chip light illuminated. A PAN was called and aircraft returned to base with the #2 engine at idle. Engineering investigation found minor (insignificant) debris on the engine chip plug. The engine chip detector was cleaned and the aircraft returned to service.
