Re: Aussie Horn Installation
Sorry it took so long to get back to my story , FWIW here it is . In order to comply with this AD you MUST use all new hardware . See Assembly Instructions Step 14 for the horn & torque tube bolts and Instructions for Continuing Airworthiness Service Manual Supplement( FAA STC ) Step 58 and59 for the Stabilator Halve bolts . You have two choices for the Stab. bolts , one is Cadmium plated and the other is Stainless Steel . The Cad. plated bolts will require a repetitive
500 hr. inspection while the Stainless bolts do not . I chose to go with the Stainless bolts and found them hard to find and very expensive ( $70.00 each ) . They are "close tolerance" bolts , but I thought $280.00 for 4 bolts was a bit much so I cranked up the old computer and found a better deal . A company called Genuine Aircraft Hardware had AN 174C32A bolts for $25.60 each so I got all four of them for $102.42 . The rest of the hardware is standard AN stuff .
As my Horn and Torque Tube arrived fully assembled the re-installation went quickly . Be sure to read the "Note" in Step 56 of the Instructions for Continuing Airworthiness Manual Supplement . It tells the kind and number of washers to use on which bolt . Remember , for the AMOC to be valid you MUST follow all instructions to the letter . The torque on the nuts is only 30 to 40 inch/pounds plus the drag of the NEW nylon lock nut .
When everything is hooked back up you MUST rebalance the stabilator . I had cleaned and lubed the old bearings the last time I did the previous AD , but the new bearings required a fair amount of weight to be added to the balance arm . The test flight went well . It might be my imagination , but the pitch movement of the yoke seemed to be just a bit smoother with the new bearings . Good luck with your airplane !
