Air Berlin did not explain the quick turn around times in Mombasa (less than 120 minutes at the gate although Air Berlin claims the aircraft was inspected to determine the source of the smells) and Munich (less than 130 minutes at the gate).
Air Berlin did not clarify how the smell of oil, that by Air Berlin's statement appeared during approach to and landing in Mombasa, was possible if the leak was static indeed and oil therefore exited the engine only while not operating and any residue had already been blown out by the operating engine evident by the dissipation of the smell of oil shortly after takeoff as reported by Air Berlin.
Air Berlin also did not explain, how it was possible that the local Bangkok maintenance team of Thai Airways while conducting the inspection of the aircraft and engines arrived at the Airbus Trouble Shooting Manual's (TSM) task 71-00-61-810-801, subtask 71-00-61-810-050-A fault isolation, identified oil leaking from the inlet cones, anti-ice vent holes, fan blades, 2.5 bleed vent areas of the #2 engine and identified puddles of oil at the bottom of the fan case of engine #2 as well as on the floor underneath engine #2, consistent with the failure of the no. 1 carbon bearing seal of the right engine. Subtask 71-00-61-810-050-A fault isolation clearly states in conclusion a) without granting any discretion: "a) If there was oil wetting in one or more of these areas, do these steps: 1) replace the engine, 2) replace the no #1 bearing carbon seal on the engine that you removed".
Air Berlin further did not explain, how it was possible that the Thai Airways' maintenance team and Air Berlin's specialist team arrived at very different results in their investigations and how it was possible that Air Berlin's maintenance team released the aircraft for a flight carrying passengers.
Air Berlin also did not explain the picture of the oil leak on the spinner (see below) that clearly shows the oil exited under the influence of sufficient airflow pressing the oil against the spinner, which entirely elimited the influence of gravity, and the spinner turning at speed, making absolutely clear the oil leaked while the engine was turning. The picture suggests by the visible distribution of oil that the picture was taken immediately after engine shut down.
