Overview
This is basically what I see.
1. Given the examination of EEC, FADEC, and appurtenant equipment,
Lack of quantity or quality of Fuel is expected to have caused this
incident.
2. A second Trent Balk at throttle was found to be not pertinent to BA38.
3. Cavitation, though found, has not been identified as Causative.
4. Everything AAIB have supplied has resulted in continuing operation of the Fleet.
5. Two major carriers have modified their fueling procedures (AA, UA).
From this a reasonable set of conclusions can be advanced.
1. Nothing AAIB have released has caused a system wide recommendation.
2. Nothing AAIB have released has caused an Airline recommendation.
3. Several reasonable theories remain which may infer other than the
resultant lack of action.
4. A responsible body as AAIB, not finding any cause to recommend
changes in equipment or procedures, has left open the door to very few
alternate albeit certainly not unobserved causative scenarios.
5. These few alternates are perforce limited to very unique and incident related possibilities. (Not generally assumed to happen again).
6. Microwave sensitive equipment could be adversely affected by tramp signal, returning to 100% post incident functionality, without record of anomaly.
7. Destruction of the Center Tank in the Landing phase may rule out an implication of tank issues.
8. There is probably good reason to withold investigative communication from the public.
