Biman Investigation Uncovers Major Maintenance Lapses on VVIP Flight

A high-level internal investigation into Biman Bangladesh Airlines has revealed alarming mechanical negligence involving a Boeing 787-9 Dreamliner used for VVIP transit. The report, submitted by a three-member committee led by Deputy Chief Engineer Md. Mansurul Alam, highlights how the aircraft was cleared for flight despite repeated engine-related defects and "unusually short" maintenance windows.

The investigation focused on a series of technical glitches occurring between December 9 and 17 last year. A recurring fault in the Variable Frequency Starter Generator (VFSG)—a component critical for engine start-up and power—was recorded three times within 15 days but remained unresolved.

The committee noted that on December 10, maintenance was rushed through in just two and a half hours, a timeframe deemed insufficient for a complex Dreamliner inspection. This negligence culminated on December 21 during flight BG-202 from London to Sylhet, where the VFSG failed mid-air, risking a catastrophic gearbox fire. Despite these red flags, the aircraft was subsequently deployed for a VVIP flight carrying the current Prime Minister on December 25.

The report categorizes the incident as a "major administrative failure," citing a financial loss of approximately Tk 26 crore.

These costs stemmed from Repeated, ineffective parts replacements. "Cannibalizing" parts from other aircraft. Emergency logistics for last-minute repairs.

The committee identified engineers Hiralal and Md. Saifuzzaman Khan for significant lapses, including clearing the aircraft for takeoff despite low fuel pressure warnings. The report recommends strict disciplinary action against the duo for endangering lives and state property. Biman officials have acknowledged the report but declined further comment.
