SYNOPSIS
On 1 June 2008, an Airbus A320 aircraft, registration PK-YVE, was being
operated by Metro Batavia Airlines (Batavia Air) flight number 7P-591, on a
scheduled passenger flight from Jakarta to Medan. The flight departed at 00:10 UTC
(07:10 local time) with an estimated arrival time at Medan of 02:25. There were 140
people on board; two pilots, five cabin crew, and 133 passengers.
The aircraft touched down towards the departure end of the touch-down area of
runway 05 at Polonia Airport, Medan at 03:04. After a landing run of 41 seconds, the
aircraft stopped on the runway adjacent to taxiway ‘D’, approximately 1,200 meters
from the estimated point of touch down. Three main-wheel tires and two main
wheels were substantially damaged. The aircraft could not be taxied from the runway
to the apron, nor could it be towed to the apron due to damage to the wheels.
The passengers and crew disembarked normally at taxiway ‘D’; there were no
injuries.
Following an inspection of the landing gear and replacement of the damaged wheels,
the aircraft was towed to the apron at 10:10. The runway was closed for about 7
hours.
The investigation found that the left landing gear down-lock cable was broken. The
aircraft touched down with the wheel brakes locked due to a hydraulic lock in the
system, which was the result of an incorrect manual landing gear extension
procedure being used by the pilots.
The pilots’ actions indicated that they did not sufficiently understand the aircraft’s
landing gear system, resulting in them using inappropriate trouble shooting and
rectification procedures.
The pilots were not sufficiently confident of the aircraft’s fuel state to conduct a go
around and fly past as cleared by ATC.
With the release of the final report, the National Transportation Safety Committee’s
(NTSC) issued two recommendations to address the safety deficiencies identified in
the report. These covered flight crew technical knowledge of aircraft systems, fuel
planning and flight management, and the regulatory oversight of the airline’s training
program.
