This info comes either from the horse’s mouth or was published in June’s Pilot mag.
The RAF worked to a Fatigue Index of 114 which equates to 5000 civvy hours.
The major mod BH193 plus some minor mods (at the sort of prices previously mentioned) gives an extension of the FI to 200 or 4320 extra hours but with an overall total of 8760 airframe hours. Most of the ex RAF Bulldogs are at or near FI 114. Because the RAF incorporated many mods, these aircraft are not considered the same as series 120 so are being re-certified as series 121. The Bulldog Owners Group seem to be driving this and expect to recoup costs by a c£4K fee on those ‘planes that eventually reach the register. Contact for the BOG is

[email protected] I've flown some ex-Botswana ones and I've got to say they could be expensive for their owners. ADs on the most unlikely things; a pig for the engs. to work on. Fuel consumption high. Roll cuff on the LE to achieve washout = draggy. Compare with a non-aerobatic PA28 Arrow on the same engine and there is no comparison. They're aerobatic that's all.
