Porter Airlines – DHC-8-402 – Hydraulic Leak


C-GKQE, a Bombardier DHC-8-402 aircraft operated by Porter Airlines, was conducting flight POE388 from Chicago/Midway Intl, IL (KMDW) to Toronto/Billy Bishop Toronto City, ON (CYTZ) with 4 crew members and 41 passengers on board. During the approach into CYTZ, the flight crew noted that the number 2 hydraulic system quantity was indicating 25%. When the landing gear was selected down, the system dropped lower to 20%. The flight crew informed ATC to check the runway for hydraulic fluid after the aircraft lands.

During the landing rollout, numerous caution lights associated with the hydraulic system illuminated. The aircraft was taxied clear of the runway and both engines were shut down. ARFF met the aircraft and confirmed hydraulic fluid leaking from the nose landing gear area.

The aircraft was then towed to the gate. The operator’s maintenance found a flexible hydraulic line leaking on the nose landing gear.
