An Embraer EMB-145LR aircraft, 5N-BVD, operated by Air Peace, was a scheduled passenger flight (four sectors); Lagos-Owerri-Lagos and Lagos-Kaduna-Lagos, using the same flight crew.
At 10:27 h, 5N-BVD departed Murtala Muhammed International Airport Lagos (DNMM) for Kaduna airport (DNKA) for the third sector as flight APK7376 on an Instrument Flight Rules (IFR) flight plan with 53 persons on board. The First Officer was the Pilot Flying (PF), while the Captain was the Pilot Monitoring (PM).
During climb out of Lagos, an Advisory Light HYD1 LO QTY on the Engine Indicating and Crew Alert System (EICAS) came ON and the QRH was accomplished. The hydraulic fluid level indication was monitored until landing in Kaduna.
While preparing for the fourth Sector, in Kaduna, the Electric Motor Driven Pump (EMDP) was used to power the Hydraulic System. During Taxi, the Lead Cabin Crew informed the flight crew that there was an unusual sound from the over-wing to the aft of the aircraft. The flight crew concluded that the sound emanated from the EMDP and continued with pre-flight activities.
The aircraft lined up for take-off and as it accelerated towards 119 kt, the take-off was aborted, thus initiating a sequence of events that eventually led to the failure of Number 1 and Number 2 Wheel Assemblies and additional damage to the aircraft.
Causal factor
Operating the aircraft with an unserviceable hydraulic system leading to a high speed rejected take-off.
Contributory factors
1. Leakage of Hydraulic System 1 due to a loose coupling on the hydraulic line servicing the Brake Control Valve.
2. Non-adherence to Air Peace Limited guidelines on diagnosis and reporting of faults.
3. The non-detection of a hydraulic leakage and non-indication of HYDRAULIC SYSTEM FAIL message on the Engine Indicating and Crew Alerting System (EICAS) reinforced the flight crew decision (confirmation bias) to continue with the flight.
