Air India crash report delayed as engine examination by GE Aerospace remains incomplete

The final investigation report into the Air India Boeing 787 crash is expected to face delays as key technical analysis of the aircraft’s engines remains incomplete, according to people familiar with the matter.

The Aircraft Accident Investigation Bureau (AAIB) is still awaiting detailed findings from engine examinations being carried out in coordination with GE Aerospace, which has slowed down the completion of the final report.

The crash, which occurred on June 12, 2025, involved Air India Flight AI171 operating from Ahmedabad to London Gatwick. The aircraft crashed shortly after takeoff, resulting in one of the deadliest aviation disasters in India’s history.

Investigators have been focusing on multiple technical and operational aspects of the crash, including the aircraft’s fuel control systems and engine performance data. However, the ongoing engine analysis has emerged as a key factor delaying the final conclusions.

According to sources, while international aviation rules generally recommend that accident reports be published within a year, the complexity of the investigation and pending technical inputs have made it difficult to meet the timeline. Authorities are now expected to release an interim status update before the final report is completed.

The investigation has already drawn significant global attention due to early findings suggesting a sudden loss of engine power shortly after takeoff. However, officials have not yet reached a definitive conclusion on whether the incident was caused by technical malfunction, human factors, or a combination of both.

A preliminary report released earlier had indicated that both engines may have lost thrust after fuel control switches moved to the “cutoff” position, but investigators continue to examine all possible scenarios, including mechanical and system-related issues.

The delay underscores the complexity of modern aircraft accident investigations, particularly those involving advanced systems such as the Boeing 787 Dreamliner.

The probe continues with assistance from international aviation safety agencies, engine manufacturers, and technical experts.
