Oil seeps by the piston rings and accumulates in the combustion chamber of lower cylinders. impact damage to another, usually stationary and unoccupied, aircraft caused by undetected relatively minor impact which is then not detected prior to either damaged aircraft departing on a flight. As Lisbon had no de-ice facilities, it was towed to a location where the sun would melt the ice more quickly but during poorly-planned manoeuvring, one of the wingtips was damaged by contact with an obstruction. The Investigation attributed the ice which led to the problematic re-positioning to the operators policy of tankering most of the return fuel on the overnight inbound flight where it had become cold-soaked. Later another aircraft, positioned behind the A321, confirmed the rudder damage. Or can it? Damaged or defective equipment is dangerous, often resulting in injuries to personnel or damage to equipment and aircraft, so all equipment used for towing aircraft should undergo regular maintenance and, crucially, it should be inspected at the beginning of each shift. Pilots tend to taxi faster on runways than taxiways, exacerbating this problem. On 4 June 2002, the crew of an MD82 in the cruise at FL330 with AP and A/T engaged failed to notice progressive loss of airspeed and concurrent increase in pitch attitude as both engines rolled back to thrust levels which could not sustain level flight. As part of out of service repositioning of aircraft supervised by maintenance personnel, it may follow thePushbackfrom a nose-in gate of an empty aircraft with engines off.
