Incident at GREATER MONCTON ROMEO LEBLANC INTERNATIONAL AIRPORT

Summary

2010-11-15: UPDATE Maintenance & Manufacturing: Shortly after takeoff white smoke appeared in the cockpit which prompted the crew to declare an emergency and return to Moncton. They landed without incident and taxied to the hangar followed by the emergency services. The fire crew used the thermal imager to look for signs of hot spots but they were unable to identify anything unusual. Upon investigation it was found the right hand engine Accessory Gearbox (AGB) breather hose was partially blocked restricting the release of pressure from the AGB. This pressure build up resulted in flooding of the bearing housings and migration of oil into the compressor and aircraft environmental services.
2010-11-26: UPDATE TSB: A10A0120: SLQ7073, a Skylink Express Beech 1900C departed on a cargo flight at 0604 AST from Moncton (CYQM) for Halifax when at approximately 10 miles out, the crew noticed white smoke in the cockpit. The crew declared an emergency, requested immediate vectors and returned to CYQM with ARFF standing by. The aircraft landed safely at 0615 on Runway 06 without further incident and were followed by ARFF to a shutdown position on apron. The crew of two evacuated the aircraft uninjured and there were no passengers. Thermal imaging inspection by ARFF revealed no evidence of fire and the smoke quickly dissipated. Further inspection by company maintenance staff found that, during work performed prior to this flight, the number two engine oil breather hose had been installed so that its inner hose material restricted normal venting of crankcase pressure. Excessive engine crankcase pressure after take-off caused oil to migrate into the engine compressor and then vaporize causing subsequent smoke ingress into aircraft environmental system via compressor bleed air. The oil breather hose removed was believed to be standard SCEET hose but had no markings. A new hose with the part number as identified in the Beech 1900 Illustrated Parts Catalog was installed to correct the problem and the aircraft was released to service.
2010-11-08: SLQ7073, Beech 1900C, enroute from Moncton (CYQM) to Halifax (CYHZ), departed at 10:04Z and declared an emergency at 10:07Z due to smoke in the cockpit. Aircraft Rescue and Fire-fighting (ARFF) were on standby. SLQ7073 landed safely at 10:15Z. Thee was no impact on operations.
