Tony was on exchange to 824: Dave Mallock was driving a FGN Sea King and encountered severe torque fluctuations when returning to CU, so bad that he did an engine off into a ploughed field on the Lizard. He thought the machine was about to turn over as he slid through the mud, reckoned that he saw ~30 degrees on the AI before it stopped more or less upright
Tony was having problems, too, and broke off his approach into CU on hearing Malarkey Jim's Mayday and went back to provide help if required. When Malarkey called safe on the ground, Tony made the intelligent decision to land: just near the local pub
AFC's to both of them, well deserved. Problem was salt accumulation on the IGV's following protracted low level ops in gale force winds and associated ocean spray. Quite a few more years before the barn doors appeared, IIRC, even though the USN and most other Sikorsky SK operators had used them for ages
