PŘÍKAZ K ZACHOVÁNÍ LETOVÉ ZPŮSOBILOSTI ÚŘAD PRO CIVILNÍ LETECTVÍ ČESKÁ REPUBLIKA Sekce technická letiště Ruzyně, 160 08 Praha 6 tel: 233320922, fax: 220562270 Číslo: 2007-0183 R2 Corrected Datum účinnosti: 16. července 2007 Datum vydání opravy: 6. listopadu 2007 Diamond Aircraft Industries GmbH model DA 42 Tento PZZ je vydáván pro výrobek transferovaný pod působnost EASA Na základě rozhodnutí EASA je následující Příkaz k zachování letové způsobilosti závazný pro všechny výrobky provozované v EU, na které se daný PZZ vztahuje. Provedení PZZ, který se vztahuje podle typu a výrobního čísla na výrobek je pro provozovatele/vlastníka letadla zapsaného do leteckého rejstříku závazné. Neprovedením PZZ ve stanoveném termínu dojde ke ztrátě letové způsobilosti výrobku. Poznámky: - Provedení tohoto PZZ musí být zapsáno do provozní dokumentace letadla. - Případné dotazy týkající se tohoto PZZ adresujte na ÚCL sekce technická. - Pokud to vyžaduje povaha tohoto PZZ, musí být zapracován do příslušné části dokumentace pro obsluhu, údržbu a opravy letadla. 1/2 EASA AIRWORTHINESS DIRECTIVE AD No : 2007-0183 R2 [Corrected: 07 November 2007] Date: 06 November 2007 No person may operate an aircraft to which an Airworthiness Directive applies, except in accordance with the requirements of that Airworthiness Directive unless otherwise agreed with the Authority of the State of Registry. Type Approval Holder’s Name : Diamond Aircraft Industries GmbH Type/Model designation(s) : DA 42 TCDS Number : EASA A.005 Foreign AD : not applicable Revision: This Airworthiness Directive (AD) revises and replaces EASA AD 2007-0183 R1 dated 28 August 2007. ATA 76 Engine Controls – Engine Control Unit Back-up Batteries - Installation Manufacturer: Diamond Aircraft Industries GmbH Applicability: DA 42 airplanes, serial numbers 42.004, 42.006, 42.009 through 42.156, 42.158 through 42.176, 42.178 through 42.190, 42.192 through 42.233, 42.235 through 42.246, 42.248 through 42.254, 42.256 through 42.261, 42.263 through 42.269; and 42.AC001 through 42.AC109 (Canadian production line) Reason: Recently, a double in-flight engine shut down incident occurred on a DA42 aircraft equipped with TAE125-01 engines. The BFU (German Accident Investigation Body) found the root cause to be a violation of the Airplane Flight Manual procedures (taking-off with an insufficiently charged main aircraft battery) and momentary low voltage in the electrical system of the aircraft when retracting the main landing gear. This has been the subject of Diamond Service Information (SI) 42-040 and a subsequent EASA Safety Information Notice, SIN 2007-08, issued on 18 April 2007. The TAE125-01 and TAE125-02-99 engines, approved for installation on the DA42, are FADEC (Full Authority Digital Engine Control) controlled and are not totally independent from the aircraft electrical power supply. A significant drop of the voltage causes simultaneously a reset of the FADEC on both engines with subsequent feathering of the propeller blades. In the case of an empty battery this scenario may be considered as catastrophic at the aircraft level. The Thielert Aircraft Engines (TAE) Installation Manuals IM-02-01 Issue 4 and IM-02-02 Issue 1 have been revised to address this issue, which is the subject of EASA Airworthiness Directive (AD) 2007-0182. AD 2007-0183 was issued to require installation of additional Engine Control Unit 2/2 (ECU) Backup Batteries to supply electrical power to the ECU, preventing high transient power drains from causing a short-term voltage drop when insufficient power from the main battery might exist. This AD has been revised to extend the compliance time by one month, to 30 November 2007, and to include reference to an approved alternative method of compliance. Aircraft already in compliance with EASA AD 2007-0183 or its revision 1 are not affected by this change. This AD has been republished to correct a typographical error. Effective Date: 16 July 2007 Compliance: Within the next 200 Flight Hours, but not later than 30 November 2007, whichever occurs first after the effective date of this directive, accomplish the following: • Modify the engine electrical system of the DA 42 by installing additional ECU backup batteries in accordance with Diamond Aircraft Industries (DAI) Mandatory Service Bulletin (MSB) 42-042 dated 22 June 2007 and DAI Work Instruction WI-MSB-42-042 dated 20 June 2007 or later approved revisions of these documents; and • Amend the DA 42 Aircraft Maintenance Manual by inserting DAI AMM-TR- MÄM-42-240 Temporary Revision dated 17 June 2007 or later approved AMM Revision, update the operator’s maintenance programme and maintain the aircraft accordingly; and • Amend the DA 42 Airplane Flight Manual (AFM) by inserting a copy of AFM TR-MÄM-42-240 dated 17 June 2007 or later approved AFM Revision into the AFM, as instructed in that document. Note: Modification of the engine electrical system of the DA 42 and accomplishment of related actions in accordance with the instructions contained in DAI Optional Service Bulletin (OSB) 42-050/1 or later approved revisions, including associated documents referenced therein, has been approved as an alternative method of compliance for the requirements of this AD.
