The statement for it being a Royal Marine Scout gives this as the reference -
Flying accidents in the war zone
1 Scout AH.1 Royal Marines (crash landed after main rotor gearbox failure over MacPhee Pond, 8 June. Recovered but written off.) - Ethell, Jeffrey and Price, Alfred - Air War South Atlantic Macmillan Publishing Company (1983) pp.248-251 ISBN 0-02-536300-X. I don't have that book to check though.
The same article also gives this
Aircraft Lost in the Air:
1 Scout AH.1 Royal Marines (shot down by Pucara at Goose Green on 28 May). (Same reference)
Which is confirmed elsewhere -
Scout of B Flight, 3 CBAS shot down near Camilla Creek House, north of Goose Green by Pucaras of FAA Grupo 3 (11.55 am). Pilot Lt Nunn RM was killed.
Then of course there's the separate reference you're aware of
Another Scout, XR628, of 656 Sqn AAC, suffered a main rotor gearbox failure whilst in a low hover over MacPhee Pond on 8 June 1982. XR628 had taken cover as two pairs of A-4 Skyhawks from Grupo 5 approached, these aircraft later attacked the RFA LSLs Sir Galahad and Sir Tristram at Bluff Cove. Once the threat had passed and the pilot began to climb away, the main gearbox failed at the main input drive and the aircraft made a forced landing at the lakeside in around four feet of water. The two crew were picked up another 656 Sqn Scout piloted by Capt J G Greenhalgh later that day. The aircraft was eventually recovered and airlifted to Fitzroy by Sea King on 11 June, but was subsequently written off on its return to the UK. Following research at the National Archive, Kew, it has been determined that XR628 was also the aircraft that was shot down on 26 May 1964, carrying 3 Para's CO, Lt Col Farrar-Hockley.
So far I've not been able to find the pilot's details.
