A 25-09-2001 incident occurred at Manchester Airport when a scheduled flight carrying 21 passengers and crew struck lightning during approach. The aircraft experienced an immediate left engine overheating, resulting in rapid engine parameter decrease. The commander reported radar weak returns of cumulonimbus cloud activity but maneuvered to avoid affected areas. A lightning strike caused the engine to overheat and subsequently resulted in a single-engine landing on the right engine.A 25-09-2001 incident occurred at Manchester Airport when a scheduled flight carrying 21 passengers and crew struck lightning during approach.

Description

Substantially damaged 25-09-2001: Struck by lightning on approach to Manchester Airport, and left engine began overheating. No injuries reported to the 21 persons on board (crew of 4 plus 17 passengers). According to the following excerpt from the official AAIB report into the accident: “The aircraft was carrying out a scheduled flight from Aberdeen to Manchester. The commander, who was the handling pilot, reported that during the flight the weather radar was displaying weak returns of cumulonimbus cloud activity, but he manoeuvred the aircraft in order to avoid the affected areas, primarily by visual means. He accepted radar vectors to position the aircraft downwind for the landing runway. Just as the aircraft entered cloud, a lightning strike occurred. The commander subsequently reported that there was neither turbulence nor significant precipitation at that time. Recorded data indicated that the aircraft was close to Flight Level (FL) 70 (7,000 feet) at the time with a low thrust setting. The first officer informed the commander that he had observed a left engine over-temperature indication. Within 5 to 10 seconds of the strike, both crew members noted that the left engine operating parameters were decreasing rapidly. They were not aware of any warning or caution indications at the time. A distress call was broadcast and checklist procedures for both engine failure and single-engined approach were carried out. An uneventful single-engined landing (on the right engine only)then took place at 14:15 hours.” Damage sustained to airframe: Per the AAIB report “Light fuselage skin and rivet burns. Heat damage to right wingtip”
