An aircraft which crash landed at a South Yorkshire airport due to corrosion in part of the landing gear had similar problems just two years before, according to an official report.
The LinksAir Jetstream had just landed at Robin Hood Airport Doncaster Sheffield on a flight from Belfast when its landing gear failed, causing the plane to slide across the runway in the crash on Friday, August 15, 2014.
A report published this week by the Air Accidents Investigation Branch said the planhad undergone modifications to the landing gear after a similar incident in March 2012.
However, the report concluded: “It is evident the inspections of, and modifications to, the left main landing gear were not effective in preventing this accident.”
And the AAIB called for Jetstream 31s to be checked in future.
The aircraft’s left main landing gear failed as a result of stress corrosion cracking at the top of the left landing gear cylinder – after corrosion to the right landing gear caused the 2012 incident.
The report stated: “The landing gear material is known to be susceptible to stress corrosion cracking. The investigation determined a design solution implemented by the aircraft manufacturer following the 2012 accident, which was intended to prevent stress corrosion cracking, had not met its original design intent. “In light of the findings of the investigation, the aircraft manufacturer is taking additional steps to assure the continued airworthiness of landing gear cylinders manufactured from DTD 5094.”
During the crash the left landing gear detached from its mounts, the aircraft slid along the runway and came to rest on the grass.
The Jetstream 31 plane had two crew members and one passenger on board. The passenger was taken to hospital for a check-up.
The airport was temporarily closed down with four inbound scheduled flights and three outbound services affected after the crash.
