Two Night-Time Take-off Misalignments at Seletar Airport Damage Runway Infrastructure

Casualties unknown • SG

Two separate incidents involving heavy jets at Seletar Airport resulted in runway edge light damage after both aircraft mistakenly lined up on the right edge of the runway.

What happened

Two serious incidents occurred at Seletar Airport during night operations in 2024. On 17 July, a Dassault Falcon 900EX, registration M-ILTA, departed for Muscat, Oman. During rotation, the crew heard a loud noise and later discovered the aircraft had struck a runway edge light. Upon arrival in Oman, the aircraft was found to have damage to its nose landing gear tyre and an auxiliary shield door.

On 6 October, a Bombardier Global 6000, registration T7-RIC, departed for Bangalore, India. This aircraft struck several runway and taxiway edge lights, leaving debris on the runway. Following the flight, the aircraft was found to have deep cuts to its right main landing gear tyres and a hydraulic fluid leak from the brake system.

The investigation

The investigation established that in both instances, the aircraft had failed to align with the runway centerline, instead performing their take-off rolls along the right edge of Runway 03. For the second incident, the debris from the damaged lights remained on the runway until two subsequent aircraft landed and reported the presence of foreign object debris (FOD).

Investigators examined the visual environment at the airport, noting that the absence of runway centerline lights at Seletar, combined with the specific layout of the taxiway intersection, created a misleading visual path for the pilots.

Probable cause

The aircraft were **misaligned on the right edge of the runway** because the pilots likely mistook the white runway edge lights for centerline lights, a confusion exacerbated by the lack of centerline lighting, night-time visibility limitations, and the presence of an additional paved area at the runway threshold.
