Ah yes Dazza , some Jab. owners have had engine failures, and for a variety of reported reasons , however the facts regarding those failures , are often either highly questionable , misreported or not reported at all . There are also many success stories , but we don't often hear about those , like the flying school at Moree I visited recently , who were generous in their praise for the Jab engines , and how they change their engines over at 1000 , usually trouble free hours , receiving a very attractive change over price from the factory . I am also personally aware of an instance ,where a big end bearing on a Jab 2200 ' ran ' after 100 hours on a reco. engine . The pilot kept the engine running , and returned some 5 miles back to the airstrip , landing without incident . When I checked the engine the oil level barely registered on the stick , and the bearing had all but disappeared . I believe the pilot was doing practicing forced landings with steep climb outs . If there is a fault with the Jab engines it is their minimal oil capacity , and all prudent owners check the level prior to each departure . Interestingly , in this instance , the factory agreed to cover the damage under warranty with some small contribution by the owner .
