898 was involved in an incident. The pilot was suffering from target-fixation and ended up in a dive at about Mn 1.3. He got out of it by overstressing the a/c (10-14g). I know they manged to repair it afterwards but I assume those repairs weren’t the standard mod 9. I was away from the Lightnings then but I have seen stress-relieving plate repairs on Buccs and Victors.

Has anybody had experience of the mod 9 program? Were there any visible features externally?
The extra wing reinforcement plates to the underside near the wing roots were visible….. I remember Barry Pover explaining them and pointing them out on XS898 at Cranfield in 1989(?) at the launch meeting of the Lightning Assciation…..(although, IIRC, ‘898 was done as a result of the last RAF display pilot overstressing the a/c back in 1980 after an inflight disorientation resulting in a dive at M1.3).
However, I’m not sure if MOD 9 existed prior to this, or the resultant ‘fix’ for ‘898, ended up being the guinea-pig for what became MOD 9, as I know MOD 9 did involve fitting reinforcing plates….just not sure if they were visible as per ‘898….???

About 30 mk6 a/c were modified. It was a wing-strengthening mod to increase their service-life by about 400 hours.

Excuse my ignorance – what did the Mod 9 programme introduce? Which Marks were affected?
