Air Canada – Airbus 320-200 – Landing Gear Malfunction


C-FDSN, an Airbus 320-200 aircraft operated by Air Canada, was conducting flight ACA224 from Vancouver Intl, BC (CYVR) to Calgary Intl, AB (CYYC). Shortly after takeoff from CYVR, the landing gear doors failed to close upon selection of landing gear up. Following an unsuccessful ECAM reset, the flight crew declared a PAN PAN and elected to return CYVR where the aircraft landed without further incident.
Subsequent maintenance actions revealed a leaking nose landing gear actuator. The nose landing gear door safety valve and NLG door up-lock were replaced. Note: C-FDSN experienced a similar landing gear door issue while departing Los Angeles, CA (KLAX) on 30 April 2018 (see TSB Occurrence A18F0092).
