Overview
- Dramatic passenger video showed violent shaking and sections of the cabin ceiling and interior panels detaching after a Sepehran Airlines flight departed Mashhad on Tuesday.
- The crew declared an emergency, the aircraft returned and landed in Mashhad without injuries, and passengers were moved onto another plane to complete the trip.
- Iranian authorities temporarily closed a runway for checks and opened an official investigation to determine the sequence from the tyre failure to the reported engine problems and cabin resonance.
- Reporting and flight data identify the jet as EP-FSU, a Boeing 737-300 first flown in 1996, and the incident follows recent Sepehran mishaps and U.S. Treasury sanctions that have tightened formal channels for parts and maintenance.
- Investigators and safety analysts will look for whether the immediate cause was mechanical damage from the tyre event or deeper maintenance and parts-supply shortcomings, and regulators may review grounding, inspections, or maintenance approvals depending on the findings.
