hi anyone heard about the ad on spindles .on enstrom 280 .. what are the options with this

 

It’s fairly straightforward, they are superseding AD 2015-08-51, with AD 2018-02-01 due to additional reports of cracked spindles. The new AD establishing a life limit and upgrades inspection requirements.

 

Requires establishing a spindle life limit of 1,500 hours, Time-In-Service (TIS).

 

Requires that the Magnetic Particle Inspection (MPI) be conducted by a Level II or Level III inspector or equivalent. Prior service information specifies sending the spindle to Enstrom for an MPI

 

Requires an initial MPI before further flight for a spindle with 500 or more hours TIS, unless an MPI has been done within the last 500 hours TIS.

 

Costs of Compliance

We estimate that this AD affects 323 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Inspecting the spindles takes about 15 work-hours for an estimated cost of $1,275 per helicopter and $411,825 for the U.S. fleet per inspection cycle. Replacing a cracked spindle costs $8,164 for parts and no additional work-hours. Replacing a set of three spindles that have reached their life limit takes about 14 work-hours and parts will cost $17,500 for a total cost of $18,690 per helicopter.

 

Read the AD: AD 2018-02-01

ah .how about the airwolf tt system ..nearly 20k for this on a helicopter thats got a rotorhead designed to lift 5 .280 and 480 same i think .. average 28 a worth about 40 to 50 k .i think us hobby fliers or sunday coffee drinkers are being pushed out or down the experimental route .. i wonder what sort of test the faa would conduct on the safari rotor head .dont get me wrong its a good machine .. but the whole thing is a money racket ..how can anyone justify putting nearly half the value of a machine into the rotor head ..enstrom f28a on the experimental reg .now theres an idea
