SERVICE BULLETIN #4

SUBJECT:  FE-30 ELEVATOR WELDMENT

TO:       ALL Kitfox™ OWNERS

FROM:     DENNEY AEROCRAFT CO.

 

Recently, one builder who has flown his Model 1 Kitfox™ about 400 hours noticed a crack on the elevator weldment. The crack developed on the spar of the FE—30 at the inboard junction of the trailing edge on the pilot side.

Since this juncture is covered by fabric, you should check this weldment very closely before further flight. Close inspection of this juncture should be a part of every pre-f light inspection.

We have designed gussets that need to be welded to the top and bottom of this spar-trailing edge juncture on both sides of the elevator control horn. We strongly recommend you do this as soon as possible.

All aircraft shipped from the factory on or after September 30, 1989 and beginning with serial numbers #485 will include this modification

We will provide the gussets to you upon your request, for $10.00 which includes mailing costs.

If you need assistance in any way, please call customer service, before returning any items to Denney Aerocraft Co. Please obtain a Return Goods Authorization (RMA) number from customer service.
