Key Facts

What Caused the Helicopter Fire at Subang Airport?

The helicopter fire at Subang Airport was caused by a suspected fuel line leak that ignited during pre-flight engine testing, according to preliminary findings by the Civil Aviation Authority of Malaysia (CAAM). The incident occurred on the ground, not in the air, which allowed ground crews to respond rapidly. CAAM has launched a full investigation under Section 28 of the Civil Aviation Act 1969, with a preliminary report expected within 14 days. The helicopter involved was a Robinson R44 model, commonly used for training and private charter in Malaysia. The aircraft had undergone its last scheduled maintenance 30 days prior to the incident, according to the operator's maintenance log.

"The pilot noticed abnormal fuel pressure readings and immediately shut down the engine. The fire started approximately 90 seconds later during the shutdown sequence," said a CAAM investigator at the scene.
