2 Fouga under total renovation

We are working on 2 Fouga since a couple of months to be able to have them certified under the new FAA regulation 8130-2G
It is a major work, and was called EMJ ( Major overhaul ) performed every 10 years on Fouga with Marbore II or 3200 hours, and 11 years on Fouga with Marbore VI or 3400 hours.


Why a borescope inspection is needed

I was performing a annual inspection on a fouga with real high time close to TBO for the engines, and doing the borescope inspection, that is what I found on one engine on the outer combustion chamber.

Fouga Tip Tanks spigots inspection

On every fouga when I perform a annual inspection since 1993 I do a dye check on the Tip Tanks spigots and I replace the rubber seals for the tip tanks pressurisation.
I have a friend who was performing a annual inspection on a Fouga that flew around 40 hours since the last annual inspection, and found cracks on one spigot.
I just remind you that it is not allowed to perform aerobatic maneuvers until the tip tanks will be empty.
For the safety of the flights, it should be mandatory to do a dye penetrant check on theses spigots at every annual inspection and written in the aircraft logs.
This is a safety item, if the tip tank coming off in flight, it could have disastrous consequences.

Lors d'une visite annuelle sur un Fouga, j'ai trouvé des criques sur une fusée de bidon, cette fusée avait été contrôlée il y a une quarantaine d'heures(sans crique).

Ci joint 2 photos de la fusée avec ses criques mises en évidence par le révélateur.
Attention ces criques pouvaient provoquer la perte du bidon en vol avec toutes les conséquances.
Je te suggère de faire contrôler par ressuage les dites fusées et de prévenir les propriétaires des Fouga.
Bien cordialement.
