Summary
An investigation of a Super Puma lightning strike during oil personnel transport examines rotor damage and concealed hydraulic actuator erosion. One hydraulic system lost fluid, but the aircraft landed safely. Bench testing and dismantling revealed internal damage, possibly partly from an earlier strike, prompting revised inspection procedures and flight crew guidance.
