2016-02-20 Lion Air B737-900 runway excursion at Surabaya

Narrative

The Boeing 737-900 overran the end of the runway at Surabaya by a few meters. No one on board the aircraft was injured.

Flight JT263, landed on runway 10 at Surabaya Juanda Airport in rain when the pilots were unable to come to a standstill before the end of the runway (lengh = 3000 m).

The nosewheel overran the paved edge of the runway and came to rest on soft ground.

There was local thunderstorm activity present at the time the 737 was about to land. The runway condition was wet.

Flight operations at Surabaya were disrupted for about two hours until the 737 was removed.

NOTE:
The 737 in question wears a unique hybrid color scheme of Boeing/Lion Air as a visible reference for the first factory delivered 737-900ER to the airline.

NTSC Final Report:

Findings

1. The pilots held valid licences and medical certificates.
2. The aircraft was airworthy prior to the departure, there was no report or record of aircraft system abnormality during the flight and was operated within the weight and balance envelope.
3. In this flight, Pilot in Command (PIC) acted as Pilot Monitoring (PM) while the Second in Command (SIC) acted as Pilot Flying (PF).
4. The weather deteriorated during the aircraft on approach, the visibility decreased from 6 km to 1,000 meters and the wind changed to 020/17 knots.
5. The SIC had difficulty to control the aircraft while flying manually indicated by the activation of EGPWS hard alert ‘Glide slope, Glide slope’ and the SIC advise to fly left while the PIC assisted the SIC to control the aircraft.
6. The aircraft passed the runway threshold with speed 9 knots above the target and touched down on runway 10 at approximately 552 
meter from the runway threshold.
7. After touched down, the thrust levers were not at the idle position for 20 seconds and the pilot unable to operate the thrust reverser levers. The brake pressures increment and spoiler deployment delayed.
8. The available runway of Juanda Airport with 9,842 feet length was sufficient for the aircraft to full stop in both runway braking actions good and medium with existing speed, prolong touchdown and absence of thrust reversers.
9. The combination of prolong touchdown, delay in spoiler deployment, thrust reversers did not deploy, and late of brake application had affected the landing distance required.
10. The delay of spoiler deployment, late of brake application and thrust levers not at

Contributing Factors

  • The difficulty to control the aircraft and deteriorating weather did not trigger firm action resulted in the combination of lack of communication and leadership.
  • The combination of prolong touchdown, delay in spoiler deployment, thrust levers not at idle position, and late of brake application had affected the landing distance.
