The Director General of the MAA should not be pleading with the Military Air Operator (the MOD) to fit such an essential safety system as TCAS, he should be compelling it to do so. The reason he cannot do so of course is that the MAA is a subsidiary of the MOD, and just as bizarrely the MilAAIB is a subsidiary of the MAA. Unless and until all three are separate and independent of each other, the MOD can do, or not do, as it pleases.
As to the severe shortages of qualified and experienced personnel in RAF Engineering Trades, there is an even greater shortage of engineers, both Service and CS, qualified and experienced in airworthiness provision. As the DG well knows, that was as a direct result of the MOD's deliberate policy of replacing them with unqualified and inexperienced non-engineers in Haddon-Cave's so called 'Golden Period'. Why doesn't he say so? Because the MAA is a subsidiary of the MOD!
