An A320 lands and reverse thrust fails to operate. There had been no prior warning flags in the cockpit. Maintenance staff had forgotten to remove the reverser lockout pins after servicing. The situation could have been critical if a high speed rejected takeoff occurred at the departure airfield and the crew were unaware the reversers had been locked out.
System caution lights have removed the once good airmanship requirement of the momentary testing of brakes after moving from the tarmac. However, the above incident illustrates that on this occasion a fault in reverser operation did not show up to the cockpit crew until too late
A short test of reverse idle at an appropriate point before takeoff would have revealed this maintenance defect.. Another cue for good airmanship?
