AN LAME
You can teach a monkey to ride a bike but I am likewise sure he is capable of learning to do a quick “walk-around”. Transit checks are nothing more than that !. Having spent a lifetime in the industry, I can quote innumerable times where qualified LAME’s have failed to pick up MAJOR defects like fuel or hydraulic leaks etc!. Most transit checks are nothing more than visual checks which any competent person can perform (Pilot or LAME). The railways did not collapse when they removed guards from a lot of the trains nor was the country side littered with wrecked airplanes when they removed flight engineers. Airlines will likewise not collapse because some qualified pilots perform some transit checks WORLDWIDE !
