New regulation 8130-2G

The new regulation 8130-2G will put military jets aircraft under group 4 , 5 , 6 , 7.
I have my Broussard MH1521 under Group 2 so no more 300NM radius limitation.
To be in Group 4 or 5 you need to comply strictly with the manufacturer maintenance program and you will not have limitation about the proficency area if the aircraft was never equiped with ejection seats...
Some airplanes like L29, L39 does have an ejection seat :
You do not maintain the aircraft with hot seat, you will be under Group 6 with the famous 600NM radius.
But if you maintain the aircraft strictly with the manufacturer maintenance program who call to have ejection seat, your aircraft will be under Group 7 with the famous 600NM radius.
The new 8130-2G target aircraft with ejection seats...
Take a look under that new 8130-2G.

Pencil whip overhaul on Turbomeca Marbore

I saw with some aircraft owners that some Turbomeca Marbore II and VI had a Major overhaul done on the engine by some unscrupulous person entring in the engine log "inner and outer basket inspected and returned to service IAW maintenance manual limits for serviceable "
Turbomeca never , I said never authorised a Marbore II or VI to have a major overhaul without replacing the combustion chambers ( inner and outer ).
So be careful, instead of having an engine with fake 300hrs TTSMOH total time since major overhaul, you have an engine with real 2100 TTSMOH hours since real major overhaul so 300 hours past the TBO due time.
Be aware of theses pencil whipping overhauls.

Casa HA200 engine damage






After a call from a owner of a CASA HA200 who had vibrations on his right engine, I went to look after the problem.

The turbine blades was damaged beyond repair, a cooper seal was replaced by a so called garlock seal between tail pipe and engine ( only on Casa Jets ) who was manufactured without testing it, was coming apart and letting hot exhaust gas out in the engine compartment who could create an engine fire with all the oil and fuel lines in the area, it was a good call from the owner because it coud end up to a worst end.


Conclusion: engine need to be replaced.


More investigation will be done to find the reason why the turbine blades was damaged.
