March 13, 2020

Incident at DEDKI intersection

A Jazz de Havilland DHC-8-402 (C-GGOK/JZA7963) from Montreal/Pierre Elliott Trudeau, QC (CYUL) to Toronto/Billy Bishop, ON (CYTZ) declared a PAN PAN due to shutting down Engine #1 for oil pressure. JZA7963 landed Runway 24L at Toronto/Lester B. Pearson, ON (CYYZ) without further incident. No operational impact.
UPDATE from Airworthiness: A Civil Aviation Safety Inspector (CASI) looked into this occurrence. This incident was caused by a failed O-Ring on the No. 1 engine scavenge oil filter. The scavenge oil filter was replaced on the overnight work package in CYUL and this was the first flight afte. A leak check was carried out as per the Aircraft Maitenance Manual (AMM). CYYZ maintenance found the No. 1 engine soaked in oil and troubleshooting led to a leak at the scavenge filter bowl and failed O-ring. The O-ring was replaced, engine runs carried out, and the aircraft returned to service. There has been no recurrence. A Safety Management System (SMS) report was filed by maintenance and a follow-up was conducted by Quality Assurance (QA). The follow-up suggests the left engine oil scavenge filter cover packing was damaged during installation and this condition went undetected during the post installation leak check.
UPDATE TSB Report #A20O0030: C-GGOK, a De Havilland DHC-8-400 aircraft was conducting Jazz Aviation LP flight JZA7963 from Montreal/Pierre Eliott Trudeau (CYUL), QC to Toronto Billy Bishop (CYTZ), ON.
