TSB Update. TSB file # A01A0002: The Bae 146 aircraft was en route from Deer Lake to Halifax when the # 2 engine (Textron Lycoming ALF502R) fire warning activated. Engine power was reduced to idle but the fire warning remained active so the crew secured the engine and fired one of the fire bottles after which the fire warning stopped. The crew elected to divert to Sydney and requested that the airport fire fighters be placed on standby for the landing. The aircraft landed without further incident. A #2 engine fire warning indication incident occurred on this aircraft on 05-01-01 (A01A0001), however, an examination of the engine following that incident did not reveal any evidence of fire or faults with the fire detection system so the aircraft was returned to service. This was the second flight following that incident. In this incident, evidence of fire in the form of a melted grommet and sooting on the exterior of the tail pipe was found. Maintenance determined that a crack had developed, in the area of the #6 and #7 scallops, on the fuel manifold. An NDT inspection had been carried out in accordance with service bulletin (SB) instructions 760 cycles prior to the occurrence. The operator is re-evaluating the SB to determine whether or not the instructions and/or equipment are adequate to detect cracks in the area where they developed on this manifold. An SDR will be submitted to TC.

MAX23 PA27 enroute from Yarmouth landed in Sydney. Approximately 30 minutes later, four people believed to be passengers from MAX23 were observed walking away from the aircraft to the ramp across a grassy area onto runway 01/09. They then proceeded south through the intersection with 07/25 and into the barricaded area that was closed for a drag racing event. At the time of the incident runway 01/09 was closed via NOTAM ,and runway 07 was active with C-FYAU C404 backtracking for departure to commence circuits, and ARN897 BA46 on downwind . Both aircraft were advised of the incursion. The C404 chose to continue it's departure sequence on the 7070 foot runway and lifted off after the pedestrians were south of the runway edge.

Partial electrical restored and flight landed without further incident at 2345Z. TSB Case Closed More Information to follow. Update September 5, 2000. TSB file # A00A0140: ARN 892, an Air Nova BA146-200 was en route IFR CYHZ to CYYT at FL 270 when the #1 Gen, AC #1, and ESS AC power supplies dropped off line. A reset was attempted as per the checklist, however, this was unsuccessful. Control was transferred to the F/0. The F/0's instrument lights went black for a split second which caused the Capt. some concern at the time. Afterwards, the F/0 thought that he may have inadvertently bumped the reostat to cause this. A pan was declared by the crew for priority landing and the aircraft landed without further incident. ERS was available for landing. ACTION Maintenance reset the bus fault from the avionics bay and the system was checked serviceable. The IDG chip detector was also reset. Numerous checks were done, and as maintenance suspected that the #1 GCU was the cause of the incident, the #1 GCU was replaced.

ARN 889 BA46 departed St, John's enroute to Montreal and diverted to Halifax with cracked windshield. No assistance required. Aircraft landed safely at 1324Z Nil TSB

ARN888 BA46 on short final Runway 11 executed missed approach due problem with flaps. Subsequently reported flaps inoperative, held for 40 minutes to burn fuel, and landed Runway 29 at 0141 UTC. Flight had to remain on runway for 15 minutes to allow brakes to cool. Nil impact on traffic. TSB Case Closed more to follow. Update: No further action TSB file # A00A0036

ARN897 BA46 departing Halifax for Montreal reported a gear problem 2 nm north west of Halifax. Pilot requested a return to Halifax. No assistance required. Aircraft landed at 2352. This aircraft was involved in a similar occurence earlier in the afternoon. Nil TSB Update: The first event CADOR 2000A0044 was a return to Halifax because the gear would not come back up after take-off (even with another cycle). In Halifax, maintenance tried to reproduce the problem, did several gear swings, inspected for ice/slush, inspected all associated wiring, sensors, up-locks, and gaps. No fault found. When aircraft departed (CADOR 2000A0045) the next time, the exact same problem was encountered and they returned to Halifax again. Maintenance, as part of their trouble shooting, worked back through previous maintenance actions (night before) and found that one of the gear area panels had been swapped from another aircraft. Although this should not have had any such effect, they investigate this issue. Inspection still revealed no problems. The maintenance crew then physically pushed on the panel when doing gear swings to try and duplicate the effects of air/wind load on the panel in flight. They discovered that there was a reduction in the gap between the panel and gear. When hand pressure was applied, and they successfully reproduced the fault. They shaved back the panel (minute amount made the difference) and this rectified the problem. Appears to be a "one-of" combination of a certain aircraft and panel resulting in a slight change in the gap with wind load. They went back and checked the aircraft that was involved in the original panel swap and all checked out fine (gap clearance). Information on file MAH Moncton.

ARN883 BA46 departing Halifax rejected two take offs 25 minutes apart. No assistance required. First case pilot reported problem with APU. Second event pilot stated that cold temperatures were causing the problems. Nil TSB Update:: APU shutdown automatically due to undetermined fault the first take-off attempt. At the time, the #1 generator was out, so the APU was the alternate - making it required for operation. When the aircraft returned to the gate maintenance control was contacted and authorised a re-start attempt. At the gate it started and ran successfully with NFF. Same automatic shutdown on second attempt. Maintenance was dispatched to Moncton to repair. APU IDG oil was found to be low, just at the threshold for auto shutdown. Oil was topped up, APU was run, and no obvious leaks could be detected. Everything then worked fine (maintenance stayed on-board for the remainder of flight itinerary). While at Halifax overnight, APU IDG was removed and inspected. Carbon seal was found to be weeping oil, new seal installed. Information on file MAH Moncton

ARN891 BA46 departing Halifax advised of an Engine Indication problem and request return to Halifax. No emergency declared. Flight landed without incident 1633z. Nil TSB Update:The engine vibration indicator was jumping between 0.8 and 1.4, although vibration was not consistently noticeable. At Halifax, maintenance metered and meggared wires - no problem found. Analyser was used to check engine and components from frequencies - no problem found. Finally, through the trial and error process, it was found to be the computer (P/N 6610M43), which was replaced, rectifying the problem. Company will be checking to see if similar occurrences have been noted with this aircraft in the past.
