Bill,

I fly a 4-P Turbine and the description from Mic= helle at Kit Components is...

160-0002, gas spring 100#, 10.71" ext'= d / 3.94" stroke, M6 male

Note that there are two different "end" st= yles and confirm with her which one that you have before ordering. She is v= ery helpful!!

Dom,
My 360 requires a strut forc= e somewhere south of 65 lbs to lock the gear in flight.  The strut whe= n new at ~100 lbs has a huge margin.  I base my replacement interval o= n actual strut performance in-flight.  I look for the maximu= m airspeed at which the gear will lock.  I start at 120 KIAS and free-= fall the gear.  New gas struts will lock the nose gear even at this mu= ch elevated speed.  If it does not lock, I start slowing until I ge= t a green light.  During this test the gear has already lost its momen= tum from the free fall and it is just the  gasstrut pushing the gear f= orward into the airstream.  Once the maximum locking speed (without th= e aide of a free fall) drops below 100 KIAS I replace the strut.  = ;They have been=0A lasting about seven years.   Note t= hat undue friction in the bearings or linkages can reduce your margins = ;during the free fall.  So even if the strut is replaced more frequent= ly, an inflight test is the only way to know the actual functional performa= nce of the system.
In-flight testing of= the emergency extension is a critical maintenance item.  Throughout t= he years the Lancair fleet has suffered a number of nose gear col= lapses  (following emergency extensions) as a result of weak gas = struts that were not being properly checked.

Hello Gang,

I suggest you change out the nose= gas strut every year at your annual condition inspection. It's not worth t= he worry and they only cost 19.75ea. from Lancair Kit Components. I just or= dered a couple of them.

Fly Safe!!
