This book is a plain English, illustrated, technical guide, intended to fill in the gaps left by the FCOMs, AMM and other existing publications. It contains facts, tips, photographs and points of interest, rather than simply being a reproduction of the manuals. Its broad scope will hopefully make it as interesting to students doing their type rating as it will be to Training Captains fielding unusual and searching questions from colleagues.
The Boeing 737 Technical Guide.pdf
The first 737 went into service with Lufthansa on 10 February 1968. Generally operators were very impressed with the reliability of the aircraft from the start, although inevitably there were some technical issues found during line work. The APU had a tendency to shut down under load; this was solved by developing a new acceleration control thermostat. Engine starter valves were found to clog with sand from treated runways; this was fixed by using a finer mesh on the filter screen. Perhaps most troublesome were the integral airstairs which have a complicated way of folding and simultaneously collapsing the handrail as they retract or extend. The airstairs can still be very frustrating and in 2005 at least two UK based 737 operators decided to remove all airstairs from their fleets to avoid despatch delays, further maintenance costs and giving a 177kg (390lbs) weight saving every sector. The first 737s had twice the problems because many aircraft were also fitted with rear airstairs which were, if anything, more complicated. Other minor issues were nosewheel corrosion, ram air inlet problems and hydraulic line failure, all of which were sorted out within a couple of years. 2ff7e9595c
