1.4 Rudder Pedal Cable “S” Tubes

(Information)

Reported by Mike Derwent of Cranwell Gliding Club

The rudder cable has sawn through the forward section of the metal “S” tube

guide inner wall. The hard nylon sleeve had long since deteriorated.

This highlights the importance of ‘slipping’ the cables to inspect for wear in the

cable and guide tube or fairlead and that if anti wear inserts are fitted by the

manufacturer they must be replaced if worn or damaged

3.2 BGA Compendium of Airworthiness Directives

a) Please note that the BGA TNS and Compendium of Airworthiness Directives does not include the mandatory requirements for Tugs. Reference should be made to the relevant official publications.

b) As established last year, the BGA Compendium of Airworthiness Directives will not be sent out in paper format to inspectors. If a paper copy is really needed, remembering it won’t be updated from the start of the year, please contact the office.

c) It is recommended that you download a copy of the relevant Compendium sections, for the particular aircraft type when doing the C of A, from the BGA web site. The web site version will include all updates from the TNS and you will only have to refer to the latest TNS to ensure that the update is included.

d) The format of the Compendium will gradually be changing to separate the Mandatory requirements and “in service reports (advisory)” as some of the sections are getting very long. See the PZL/SZD Bocian for an example.

Compliance Statement: All mandatory inspections and modifications have been included up to the following; Airworthiness Notices, Contents issue 133 Mandatory Aircraft Modifications & Inspections Summary, issue 277 FAA Summary of Airworthiness Directives. Bi-weekly listing 2003-25 Foreign Airworthiness Directives Vol. I and II – CAA Additional Airworthiness Directives, issue 350 Foreign Airworthiness Directives Vol III, issue 361
