Hi Pronto
Your "crashes" would probably have been 13Sqn's
PR.9s. The list below gives all the Canberras (nine) that crashed at or near Malta.
1 WF926,
PR.3 (39Sqn) - 21/Jan/1960. Crashed in sea 19 miles ENE of Luqa - 2K.
2 WH921, B.2/U.14 - 6/Oct/1961. Shot down by Sea Slug from HMA Girdleness, Malta.
3 WJ758, B.6 (12Sqn) - 12/Dec/1957. Wheels up landing at Ta Kali, Malta.
4 WJ761, B.6 (9 Sqn) - no date. Hit parked Canberra WH973 at Luqa.
5 WT364, B.6/B.16 (249Sqn) - 26/Aug/1968. Port u/c collapsed on landing at Luqa.
6 WT481, T.4 (39Sqn) - 2/Jun/1965. Into sea 35 miles SW of Luqa.
7 WT530,
PR.7 (13Sqn) - 7/Dec/1978. Engine failure on t/o, Luqa.
8 XH130,
PR.9 (13Sqn) - 25/Mar/1969. Crashed at Hal Far on approach to Luqa, 2K
9 XH164,
PR.9 (13Sqn) - 7/Jan/1969. Crashed on appraoch to Luqa, 2K.
That's the basic list of all terminal (Cat 5) Cans at/near Malta, can see no overt "trend" though, will check some other books. Maybe JohnF has an accident record for one or more of the above, especially the
PR.9s.
Hope this helps.
(Thinks . . .maybe I should put a list of all Canberra crashes on my web-site. Would it be worth it do you think?)
