Underwriters' viewpoint ?
@ Cool Guys, re your point 2 : I can't see how the Stainless Steel casing has in any significant way changed the occurrence probability of 'Battery Unserviceable' as an EVENT; (refer to cockney steve in post # 1446) the present-day statistics show some 150 such events in 50,000 flight hours ... the question then comes : is this a 'no-go' event ? The next question is : what is the duration of 'change battery' as a line maintenance task ? (consider that henceforth the battery is to be encased in a sealed - explosion-proof - box, did you count the number of bolts/nuts = 52 ? - what about 'visual inspection' ?) Corollary : does this imply an aircraft change ? ... whence the possible concern of Underwriters : what exactly are we insuring, and for what premium ?
