FAA Special Airworthiness Information Bulletin NE-10-05 (Advisory) 1 Potential hazards and problems of aircraft engines with float type carburettors. The FAA recommend the following overhaul periods for carburettors TNS 4-2009 Whichever occurs first: o The engine manufactures recommended interval o 12 years o 2,400 operating hours. The BGA point out this is an FAA recommendation only but would add to the list; consider overhaul when abnormal operation or running is experienced. http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgSAIB.nsf/0/f54b620f79e828c18625765 1006a73b6/$FILE/NE-10-05.pdf EQUIPMENT 9. Narco AT-150 Transponder AD 2009-0200 (Mandatory) SB AT150 No 1 & No 6 Erroneous mode C altitude replies to SSR interrogations from aircraft equipped with AT- 150 transponders. http://ad.easa.europa.eu/blob/easa_ad_2009_0200.pdf/AD_2009-0200_1 General Information 1. ARC Printing Issues There have been several instances of information on Airworthiness Review Certificates (ARC) being hand written or corrected by hand. This is unacceptable. Everything, with the exception of a written signature (and possibly your inspector number), must be printed. A significant number of ARC's are being issued with the incorrect expiry date year. Don’t forget to check that the expiry is nominally 12 months after the issue taking into account the dating protocol. Remember to check all the information on the ARC for mistakes as sorting them out afterwards is time consuming and the aircraft may be grounded whilst the issues are being resolved. 2. Airworthiness Review When carrying out an airworthiness review it is required that you check ALL items including ALL Airworthiness Directives. The BGA 276 specifies that you should sample a minimum number of documents, this means that you should check all, and then sample in depth as required. For example, In depth sampling could mean taking an AD and physically checking it on the aircraft and then reviewing the associated worksheets and log book entries to confirm the task was carried out and recorded in accordance with the AD. The BGA 276 has been amended to reinforce this requirement. 3. ARC Dating Protocol BGA ARC signatories are reminded to pay attention to the ARC dating protocol as published by the CAA and reproduced in AMP 3-11 when raising an ARC. The BGA and CAA will be checking these dates and will reject any ARC's found not to comply will be rejected and may result in the aircraft being grounded whilst the issue is resolved. 2 DATING PROTOCOLS The following anticipation period may be used: Up to 90 days in anticipation of the issue of an ARC. For the issue of an ARC: TNS 4-2009 Anticipation less than 90 days prior to expiry of the ARC: The ARC issue date is from the day the ARC is issued. The expiry date will be one year from the expiry date of the last ARC. Anticipation more than 90 days prior to expiry of the ARC: The ARC issue date is from the day the ARC is issued. The expiry date is One-year from the review date for an ARC 15B Expired ARC The ARC issue date is from the day the ARC is issued The expiry date is one year less one day from the Airworthiness Review survey date NOTE 1: Where the anticipated period is within ninety days, both airworthiness review and survey must be carried out within the ninety days anticipated period. NOTE 2: Where the anticipated period is greater than ninety days, both the airworthiness review and the aircraft survey must be carried out within the ninety days preceding the recommendation date. NOTE 3: If the ARC issue is more than 90 days anticipation from the expiry of the old ARC, all the anticipation period is lost. 4 Changes to CAP 747 CAA have published AIRCOM 2009/12 advising of changes to CAP 747 due at the end of November 2009. http://www.caa.co.uk/application.aspx?catid=33&pagetype=65&appid=11&mode=list&type=sercat& id=51 .
