Incident Overview

Date: Friday 16 November 2001
Aircraft Type: Airbus A321-231
Owner/operator: Monarch Airlines
Registration Number: G-OJEG
Location: London-Luton Airport (LTN/EGGW) – ÿ United Kingdom
Phase of Flight: Take off
Status: Substantial
Casualties: Fatalities: 0 / Occupants: 229
Component Affected: No. 1 EngineNo. 1 Engine
Investigating Agency: AAIBAAIB
Category: Accident
A serious accident involving the failure of the No. 1 engine on a service from Luton Airport to Tenerife. The aircraft was diverted to London Stansted for immediate landing due to the engine’s recent overhaul. An ECAM Master Warning triggered, leading to the crew to close the thrust lever and initiate a controlled shutdown of the engine. The engine experienced a significant malfunction, resulting in a major loss of power and subsequent engine shutdown. The aircraft’s instruments indicated a severe condition, and the commander ordered the shutdown, which resulted in the aircraft being diverted to London Stansted. The incident involved a bright orange flame flash observed by the crew, confirming the engine failure and subsequent shutdown. The aircraft’s data indicated a reduction in N2 pressure and an increase in EGT, confirming the engine’s malfunction.A serious accident involving the failure of the No. 1 engine on a service from Luton Airport to Tenerife.

Description

Seriously damaged 16-11-2001 due to the failure of the No.1 engine on take off from Luton Airport, Luton, Bedfordshire. Aircraft diverted to London Stansted for an immediate landing. No injuries reported to the 229 person on board (220 passengers and 9 crew). According to the following excerpt from the official AAIB report into the accident: “The aircraft was engaged on a service from Luton to Tenerife and this was the first flight since the installation of a recently reworked engine at the No. 1 position. (The engine had been bulk stripped after 8,357 hours and 2,950 cycles to repair a combustor). There was an engineering note in the Technical Log requesting that TOGA (Take-Off/Go-Around) thrust be used for this take-off and the crew complied with this request. Everything was normal in the take-off up to the point of rotation, when an ECAM (Electronic Centralized Aircraft Monitoring) Master Warning occurred, with the caption ‘ENG 1 OIL LO PR’. This was followed a few seconds later by a loud bang and a significant jolt felt through the airframe. The crew noticed the instrument indications from the No. 1 engine beginning to decrease. The commander considered the apparent engine surge so severe that he ordered the first officer to close the thrust lever for the No. 1 engine. As the thrust lever was retarded it became apparent from the instruments that this engine had suffered a major malfunction and the crew completed the ECAM actions for Engine Severe Damage. Subsequent analysis of data from the aircraft’s QAR (Quick Access Recorder) broadly confirmed the crew’s recollection, with normal engine parameters until the appearance of the low oil pressure warning as the aircraft became airborne. The data confirmed that this was followed by the rundown of the No 1 engine, with the N2 (high pressure spool speed) decreasing and an increase of EGT from 510øC at rotation to 810øC 46 seconds later, during which time the engine was secured. The commander diverted to London Stansted Airport instead of returning to Luton Airport because of its longer runway and the landing there was uneventful. After the landing a number of passengers reported to the crew that, at about the time the engine failed, they saw a very bright orange flame flash from the intake of the No. 1 engine. The initial visual inspection showed that that there was a significant amount of metallic debris in the engine jet pipe but the engine failure had been ‘contained’, with no damage to any other part of the aircraft. There was no visible evidence of a bird strike or foreign object damage” Damage sustained to airframe: Per the AAIB report “Failure of No. 1 engine”.
