I was steering clear of making a rotary entry as service lives generally stretch to decades, but if the Swift maaged high single figures as the previous post suggests, may I enter the Belvedere as the rotary short-life champion.
September 61 to March 69 (7½ years) squadron service with a bit of trials unit beforehand.
Not understanding bending loads on twin-rotor machines, the powers-that-be put a (completely unnecessary?) total life of 1500 hours (IIRC) on the
airframe ... resulting in the scrapping of otherwise perfectly servicable aircraft
