Nothing wrong with the 748 though.
In 1967 I took the first RAAF HS 748 into Papua New Guinea. Previously we used Dakotas. The 748 proved a delightful aircraft to fly in PNG especially if we had to do bad weather low level circuits. We kept clear of cloud of course but the short field performance was first class. Most of the airstrips were short and with some airports being over 5000 ft above sea level with density altitudes being higher still, accurate airspeed over the fence was vital.
Unfortunately one of the pilots stuffed up his landing into a place called Wabag 7000 ft density altitude on the day. Wabag had an undulating strip and after a mis-timed flare plus too early throttle closure the aircraft hit very hard indeed.
The incident was kept quiet but during maintenance back at Canberra a few days later both engines were noticed to have slight droops. Closer investigation revealed significant airframe damage as well as damage to the engine attachments. The pilot was interviewed by the CO. He somehow convinced the CO that it wasn't his fault the landing was heavy but the fault of the undulating runway. The gullible CO took his word as an officer and a gentleman and subsequently we stopped using the 748 in PNG except for sea level sealed surfaces. A real pity as it was a fine aircraft in the Highlands providing a modicum of good airmanship was used.
