Circa 1981.
411A is due for an L1011 proficiency check (sim unavailable) and the check Captain mentions that we need to do some 'maneuvers' prior, which included a high speed taxi run.
Two high speed taxi runs were completed, nose wheel steering/brakes checked OK, so then off we went for the PC.
We return.
The maintenance folks are standing by for the taxi/test flight report.
The result?
Nil defects.
And this after a 'D' check.
Those familiar with these heavy maintenance checks will understand...nil defects are quite unusual.
This particular middle east airline (SaudiArabian) used (exclusively) Trans World Airlines personnel for their maintenance (then).
Nil squaks?
Par for the course with TWA.
I kid you not...TWA was very
very proficient with maintenance procedures.
The absolute best I have seen in forty years of airline flying.
Of course, TWA was absorbed by AA....downhill ever since.
