CAA C of A (Motor Gliders and Tugs) Welding may only be carried out by a CAA or JAR 145 approved welder with the correct approvals for the type of weld. All Aircraft (BGA and CAA C of A) All welding jobs must be over signed and certified by a BGA inspector or LAE with the correct authorisations. The welder is only signing for the Welding and not for the repair, modification or other job. It is the responsibility of the BGA inspector or LAE certifying the work to ensure that the welder has a current welding certificate and you should ask to see it from time to time. (a CAA welder has to submit test pieces every 6 months to remain current) You should enter the welders approval number in the aircraft documentation. 3.2 Motor Glider and Tug C of A Renewals When completing CAA C of A renewals PLEASE make sure that the information sent to the BGA is correct and complete. The majority of delays are because the engine or propeller type is incomplete or the flight hours/cycles are incorrect. You must fill in all the details – Make, Type and suffix (e.g. Limbach L2000 EA1). The CAA will reject or delay the renewal whilst the data is corrected on any application that is not complete or correct. There is some confusion about the compliance statement below. This is a certification that this TNS is to a standard containing all mandatory directives etc. up to and including the revision of the master documents as stated and is a CAA requirement. When completing your motor glider C of A renewal report you should quote the latest TNS number. This implies that you have checked the BGA Compendium and all TNS issued since its publication. (As Tugs are not supported by the BGA TNS you should quote the master documents for their C of A renewals. The issues quoted may be later than in the current TNS due to publication dates). Compliance Statement: All mandatory inspections and modifications have been included up to the following; Airworthiness Notices, Contents issue 130 Mandatory Aircraft Modifications & Inspections Summary, issue 260 FAA Summary of Airworthiness Directives. Bi-weekly listing 2002-12 Foreign Airworthiness Directives Vol. I and II – CAA Additional Airworthiness Directives, issue 334 Foreign Airworthiness Directives Vol III, issue 344 CAA Mandatory Permit Directives, issue 2002/3 Jim Hammerton Chief Technical Officer 2
