Mahan Air flight 1095 returned to land at Tehran-Mehrabad Airport, Iran after suffered an uncontained engine failure.
The aircraft, a Boeing 747-300, registered EP-MNE operated a scheduled flight from Mehrabad International Airport to Bandar Abbas Airport, carrying 19 flight crew and 422 passengers. The aircraft departed from Tehran at 07:16 hours local time.
About 07:18, while climbing through 7500 feet, the no.3 General Electric CF6-50E2 engine suffered an uncontained failure. Some parts of the engine detached and struck engine no. 4, as well as aircraft structure. The aircraft hydraulic systems no 1, 3 and 4 failed due to impact of debris from engine no.3. An emergency landing was made back at Tehran at 07:53.
Investigation revealed that the engine failure was initiated by vibration as a result of unbalance of the engine HPT module, which caused crack propagation in the low pressure turbine (LPT)
CAUSE of ACCIDENT:
The operators fault to modify the ENG# 3 with AD requirement, and ineffective action for N1 Vibration which caused uncontained engine failure.
Contributing factors:
- Insufficient operator maintenance & engineering performance
- Lack of effective monitoring in operators line maintenance
- Lack of support for engine parts and mandatory information from the manufacturer
- Lack of effective monitoring in Mahan air concerning operation, training and technical divisions.
