Incident at 19NM NE WILKES-BARRE/SCRANTON INTL / WILKES-BARRE/SCRANTON, PA (KAVP)

TSB report #A19F0034: C-GLQQ, a Bombardier DHC-8-400 aircraft operated by Porter Airlines, was conducting flight POE122 from Newark/Liberty Intl (KEWR), NJ to Toronto/Billy Bishop Toronto City (CYTZ), ON with 4 crew members and 27 passengers on board. As power was reduced once the aircraft reached its initial cleared altitude of 14 000 feet after the departure from KEWR, the flight crew noticed an unusual noise coming from the engines. Simultaneously, a POWERPLANT message was received, which prompted the flight crew to execute the QRH. In the absence of abnormal engine indications, the flight crew continued to monitor the situation, and contacted the operator’s maintenance via ACARS. Following a step climb to FL180, the number 2 Propeller Electronic Control (PEC) caution light illuminated, and the number 2 propeller RPM rose to 1060. The flight crew executed the QRH one more time, shut the number 2 engine (Pratt & Whitney Canada PW150A) down, declared an emergency, and elected to divert the aircraft to Wilkes-Barre/Scranton Intl (KAVP), PA where it landed without further incident with ARFF standing by. Following an inspection, the aircraft taxied to the terminal building. Maintenance personnel determined that the number 2 Beta Feedback Transducer (BFT) failed, causing the propeller to initially go into an underspeed condition, followed by an overspeed condition. It was held at higher than normal propeller speeds (1060) by the Over Speed Governor (OSG) until the flight crew shut the engine down. The incident has been entered into the operator’s Safety Management System for further investigation.

June 25, 2018

Incident at 0NM N NADPI intersection

Duplicate report of 2018P1052 (AOR 234327-V1)
TSB #A18W0088: C-GFFI, a privately operated Piper PA31, was conducting an IFR flight from Edmonton, AB (CYEG) to Tofino, BC (CYAZ) with 1 pilot and 4 passengers on board. While in cruise in IMC at FL180 the left engine (Avco Lycoming TIO-540-A2C) lost power. The pilot attempted to restore power but was unsuccessful. The aircraft was unable to maintain altitude on one engine and a controlled descent and turn back to CYEG was initiated by the pilot. The area minimum altitude (AMA) in the area of the descent was 13 900 feet. The pilot declared an emergency by relaying a message through another aircraft as radio contact was lost with ATC due to terrain and being below 14 000 feet. The pilot relied on a synthetic vision terrain depiction on a personal electronic device to ensure adequate separation from terrain. While descending through 10 000 feet the pilot was able to restart the engine and the flight continued uneventfully to CYEG. Maintenance did not find any issues with the engine and the aircraft was returned to service.
A Morgan Oilfield Services Ltd. Piper PA-31 (C-GFFI) on a flight from Edmonton International, AB (CYEG) and landing at Edmonton International, AB (CYEG) advised of engine failure and requested descent. The aircraft was unable to maintain altitude and descended below the minimum IFR altitude without clearance. Using communication relay through another aircraft, C-GFFI declared MAYDAY but subsequently advised that no emergency response was required, cancelling MAYDAY. The aircraft landed without issue at 1610Z.

Incident at Erie (KERI)

TSB #A18F0261: C-GBHO, an Airbus 319-100 aircraft operated by Air Canada Rouge, was conducting flight ROU1735 from Liberia/Daniel Oduber Quirós Intl (MRLB), Costa Rica to Toronto/Lester B. Pearson Intl (CYYZ), ON. During cruise flight, the flight crew received reports of significant turbulence in the vicinity of Pittsburgh Intl (KPIT), PA. As a result, the cabin was secured early, all passengers and crew were instructed to remain seated with seatbelts fastened, and an early descent to FL230 was initiated due to ride reports which indicated more favourable conditions at that altitude. In the vicinity of Erie Intl/Tom Ridge Field (KERI), PA, the flight encountered significant turbulence which caused an abrupt change in altitude and airspeed, with the aircraft climbing to FL235. ATC was notified, and a lower altitude was requested and granted. Upon reaching FL180, flight conditions were smooth and the flight was subsequently completed uneventfully. No persons were injured, nor was any damage caused to the aircraft as a result of the turbulence encounter. The operator’s maintenance inspected the aircraft and found no faults. The aircraft was returned to service.
