Wondering if anyone else has had this issue. To be fair I have not contacted Emagair as of yet. We replace our auto spark plugs at every condition inspection and reuse the short reach adapters.
We have about 4 hours on the plane since the inspection. Taking off on runway 07 I made an aggressive low level turn to crosswind and was climbing thru 300 ft Agl when we heard a loud bang and rough running engine. We immediately told the tower we were returning and landed on runway 25 twenty knots fast in airspeed and with 15 knots on the tail. All worked out OK. The analyzer told us the issue was with number 4.
When we pulled to top cowl the problem was obvious - the plug and short reach adapter were hanging by the lead. Further examination showed that 75% of the first three threads of the adapter were missing.
Has anyone had this same experience ? We of course blamed ourselves thinking we missed torquing the number four assembly but I am questioning that now. Due to the cost of the adapters, 100 bucks for 4 we have been reusing them. We are now thinking about replacing them at every other annual.
Thoughts ?
