British Aerospace 3102 Jetstream 31 – G-CCPW

Incident Overview

Date: Thursday 8 March 2012

Aircraft Type: British Aerospace 3102 Jetstream 31

Owner/operator: Manx2, lsf Links Air

Registration Number: G-CCPW

Location: Isle Of Man-Ronaldsway Airport (IOM) – ÿ United Kingdom

Phase of Flight: Landing

Status: Substantial, repaired

Casualties: Fatalities: 0 / Occupants: 14

Component Affected: Landing Gear (Right)Landing Gear (Right)

Category: Accident

A BAe Jetstream 31 turboprop plane sustained damage during landing at Ronalsway Airport, Isle of Man. The flight, NM309, departed Leeds/Bradford Airport (LBA) and was a routine visual approach to runway 26. The crew, including a newly joined co-pilot, were flying in good weather with a wind of 210ø at 14 kt. The commander was piloting, and the co-pilot was nearing the end of their line training. The approach was executed with full flap and gear locked. Immediately upon touchdown, the aircraft exhibited a lean to the right, increased lean, and a noticeable noise. The commander initiated a left roll input to level the aircraft. As speed decayed, the lean worsened, indicating a problem with the right gear. The commander continued to apply left aileron and rudder to manage the aircraft’s movement. The left engine was shut down and feathered, and the right engine was also shut down but its propeller did not feather, suggesting damage to the propeller mechanism. The aircraft left the runway, veered to the right, and slid sideways before stopping 90ø to the runway heading. The right landing gear failed due to intergranular corrosion/stress corrosion cracking of the forward yoke pintle, mirroring a previous incident involving the same aircraft at Doncaster/Sheffield-Robin Hood Airport (DCA) in August 2014. The investigation report did not contain a probable cause paragraph.A BAe Jetstream 31 turboprop plane sustained damage during landing at Ronalsway Airport, Isle of Man.

Description

A BAe Jetstream 31 turboprop plane sustained damage when the starboard undercarriage failed on landing at Ronaldsway Airport, Isle of Man. There were no injuries. Flight NM309 had departed Leeds/Bradford Airport (LBA), UK on a flight to Ronaldsway Airport (IOM). The flight had been routine and the crew were flying a day, visual approach to runway 26, in good weather, with the surface wind reported as 210ø at 14 kt. The commander was the pilot flying (PF) and the co-pilot, who had recently joined the company, was nearing the end of his line training on type. The approach was flown with full flap and the gear locked and confirmed down by the three green gear indicators. The landing weight was estimated to be 13,448 lb (6,099 kg) and the crew recalled that the Vref was about 105 kt. Almost immediately the aircraft touched down it leaned to the right and there was an unusual noise. The commander levelled the aircraft with a left roll input. However, as the speed decayed the lean increased and it became apparent that there was a problem with the right gear. The commander continued to apply left aileron and rudder. Both pilots recognised that the aircraft was likely to leave the paved surface and so the co-pilot held the control wheel and rudder to allow the commander to apply nosewheel steering and operate the feather levers. The left engine was shut down and feathered as the aircraft departed the runway. The right engine was also shut down but its propeller did not feather as the mechanism appears to have been damaged when the blades contacted the runway. The aircraft left the paved surface, yawed to the right and slid sideways before it came to a stop 90ø to the runway heading. The right landing gear failed as a result of intergranular corrosion / stress corrosion cracking of the forward yoke pintle. This same aircraft (Jetstream 31 msn 785) suffered a failure of the left hand main landing gear while landing at Doncaster/Sheffield-Robin Hood Airport (DCA), U.K., August 15, 2014. PROBABLE CAUSE: The investigation report did not contain a probable cause paragraph as recommended in ICAO Annex 13.
