4 FAA Aircraft Certification Service AIRWORTHINESS DIRECTIVE SOCATA-Groupe Aerospatiale: Amendment ; Docket No. FAA ; Directorate Identifier 2006-CE-66-AD. Effective Date Affected ADs (a) This airworthiness directive (AD) becomes effective February 26, (b) None. Applicability (c) This AD applies to SOCATA Models TB 20 and TB 21 airplanes, serial numbers 1 through 9999 without repair REP implemented on both sides, certificated in any category. Reason (d) The mandatory continuing airworthiness information (MCAI) states there are reports of interference between the wing spar lower boom and the wheel fairing attaching screw causing an unsafe condition. The interference could, if left uncorrected, reduce the fatigue life of the wing spar with potentially catastrophic results. The MCAI requires inspections and repairs as necessary to correct this unsafe condition. Actions and Compliance (e) Unless already done, do the following actions. (1) Within the next 100 hours time-in-service or 12 months after the effective date of this AD, whichever occurs first, perform an inspection of the wing spar lower boom and repair it as necessary, in accordance with the accomplishment instructions of the EADS SOCATA TB Aircraft Mandatory Service Bulletin SB , ATA No. 57, dated December (2) If defect dimensions exceed the acceptable values given in the EADS SOCATA TB Aircraft Mandatory Service Bulletin SB , ATA No. 57, dated December 2005, or if the defect is not located in areas depicted in figure 2 of the EADS SOCATA TB Aircraft Mandatory Service Bulletin SB , ATA No. 57, dated December 2005, then the Type 1 or Type 2 repair solutions are not applicable. A written report shall be sent to the manufacturer as mentioned in section A.5 of the EADS SOCATA TB Aircraft Mandatory Service Bulletin SB , ATA No. 57, dated December In this case, all flight is prohibited until EADS SOCATA provides a repair solution or otherwise agrees to further flight. 4 BW

6 FAA Aircraft Certification Service AIRWORTHINESS DIRECTIVE EADS SOCATA: Amendment ; Docket No. FAA ; Directorate Identifier 2006-CE-62-AD. Effective Date Affected ADs (a) This airworthiness directive (AD) becomes effective February 26, (b) None. Applicability (c) This AD applies to SOCATA Model TBM 700 airplanes, all serial numbers, certificated in any category. Reason (d) The mandatory continuing airworthiness information (MCAI) states there was a report of a master cylinder yoke failure. The AD requirements are to detect defective yokes on aircraft and replace them. The aim of this AD is to ensure that normal braking is available at any time to prevent possible runway excursions in the event of failure of the master cylinder yoke. Actions and Compliance (e) Unless already done, do the following actions. (1) For the serial numbers indicated below, within the next 100 hours time in service or 12 months after the effective date of this AD, whichever occurs first: (i) For airplane serial numbers 269 and 339 and up, check the aircraft records to determine whether the original cylinder yoke or yokes in the master cylinder assembly (both left-hand and righthand) delivered with the airplane are installed. This check can be done by an owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7). (A) If you can positively identify that the original yokes in the master cylinder assemblies (both left-hand and right-hand) delivered with the airplane are installed, then make an entry in the aircraft records showing compliance with this AD per section 43.9 of the Federal Aviation Regulations (14 CFR 43.9). (B) If you cannot positively identify that the original yokes in the master cylinder assemblies (both left-hand and right-hand) delivered with the airplane are installed or if any of the master cylinder yokes have been replaced, then proceed to paragraph (e)(1)(ii) of this AD. 6 BW

7 (ii) For all airplane serial numbers, unless the action is shown not to apply per paragraph (e)(1)(i)(a) of this AD, inspect for misalignment of the master cylinder yokes from their threaded pins, as instructed in the EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB , ATA No. 32, dated December 2005, accomplishment instructions paragraph. (A) If a yoke is found satisfactory, proceed to its re-installation on aircraft. (B) If a yoke is found defective, prior to further flight, discard the yoke and install a new part number T700A (or FAA-approved equivalent part number) yoke in accordance with EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB , ATA No. 32, dated December (2) For all airplane serial numbers, as of the effective date of this AD, do not install part number ZOO.N yokes or yokes in master cylinder assembly part number ZOO.N (left hand side) and ZOO.N (right hand side), unless EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB , ATA No. 32, dated December 2005, is complied with. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: (1) It does not allow interim use of yokes found defective during inspection. FAA policy is to replace defective parts on critical systems. (2) It applies to all serial numbers. This will assure that, if any of the airplanes had the affected part number yokes installed after delivery of the airplane, the unsafe condition is still addressed. It also will assure that any of the affected part number yokes are inspected per the AD and service bulletin before future installation of these parts. Other FAA AD Provisions (f) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Staff, FAA, ATTN: Doug Rudolph, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) ; fax: (816) , has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA approved. Corrective actions are considered FAA approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number Material Incorporated by Reference (g) You must use EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB , ATA No. 32, dated December 2005, to do the actions required by this AD, unless the AD specifies otherwise.

20 FAA Aircraft Certification Service AIRWORTHINESS DIRECTIVE Pilatus Aircraft Ltd., PC-6 Series Airplanes: Amendment ; Docket No. FAA ; Directorate Identifier 2006-CE-54-AD. Effective Date Affected ADs (a) This airworthiness directive (AD) becomes effective March 8, (b) None. Applicability (c) This AD applies to Models PC-6, PC-6-H1, PC-6-H2, PC-6/350, PC-6/350-H1, PC-6/350- H2, PC-6/A, PC-6/A-H1, PC-6/A-H2, PC-6/B-H2, PC-6/B1-H2, PC-6/B2-H2, PC-6/B2-H4, PC-6/C- H2, and PC-6/C1-H2 airplanes; manufacturer serial numbers (MSN) 101 through 949, MSN 951, and MSN 2001 through 2092; that are certificated in any category. These airplanes are also identified as Fairchild Republic Company PC-6 airplanes, Fairchild Industries PC-6 airplanes, Fairchild Heli Porter PC-6 airplanes, or Fairchild-Hiller Corporation PC-6 airplanes. Reason (d) The mandatory continuing airworthiness information (MCAI) states that exfoliation corrosion in the fittings of some PC-6 airplanes was found. These fittings are installed exterior to the bottom skin of the wing skin. If not corrected, undetected corrosion in this area could lead to failure of the fitting and subsequent loss of control of the airplane. Actions and Compliance (e) Unless already done, do the following actions. (1) Within 12 months after the effective date of this AD and repetitively thereafter at intervals not to exceed 12 months, perform an inspection required by paragraph 3.B.(2) of PILATUS PC-6 Service Bulletin (SB) No , dated June 13, 2006, of the fittings Part Number (P/N) , P/N or P/N for signs of corrosion. Repair of minor surface corrosion is permitted according to the Repair and Overhaul Manual (ROM) (Report No. 1391), Chap. 2 and 4. Corrosion outside these limits is not permitted. (2) If during any of the inspections required by paragraph (e)(1) of this AD, any minor surface corrosion is found, prior to further flight, remove the minor surface corrosion (Ref. ROM. Chap. 2 and 4). (3) If during any of the inspections required by paragraph (e)(1) of this AD, any corrosion out of limits is found (Ref. ROM, Chap. 2 and 4), prior to further flight, replace the fittings in accordance with paragraph 4 of PILATUS PC-6 SB No , dated June 13, 2006, with new (retrofit) fittings P/N and/or P/N BW

21 (4) Replacement of the fittings with new (improved) fittings P/N (left hand side) and/or (right hand side) terminates the repetitive inspection for that side. FAA AD Differences Note: This AD differs from the MCAI and/or service information as follows: (1) The FAA AD is requiring repetitive inspections, not just a one-time inspection as required in the MCAI. (2) The Service Bulletin specifies subsequent inspections for corrosion will be included in Chapter 5 of the Aircraft Maintenance Manual (AMM). The only way we (FAA) can mandate these repetitive inspections is through an AD. Other FAA AD Provisions (f) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Staff, FAA, ATTN: Doug Rudolph, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) ; fax: (816) , has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act (44 U.S.C et.seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number Related Information (g) Refer to FOCA AD HB , effective date September 28, 2006, which references Pilatus Aircraft Ltd.

Effective Date Affected ADs (a) This airworthiness directive (AD) becomes effective February 20, (b) None. Applicability (c) This AD applies to Turbomeca Arriel 2B1 turboshaft engines. These engines are installed on, but not limited to Eurocopter AS 350 B3 and EC 130 B4 helicopters. Reason states: (d) European Aviation Safety Agency (EASA) AD No , dated January 9, 2007, This AD is prompted by several reported cases of rupture of the (hydro-mechanical metering unit (HMU)) constant delta pressure valve diaphragm on Arriel 2B1 engines, due to the wear of the delta P diaphragm fabric. Rupture can result in the loss of the automatic control mode of the helicopter, accompanied with a deterioration of the behavior of the auxiliary back-up mode (emergency mode). The loss of automatic control mode coupled with the deteriorated performance of the backup mode can lead to the inability to continue safe flight, forced autorotation landing, or an accident. Actions and Compliance (e) Unless already done, do the following actions. (1) Replace the HMU with a serviceable HMU before the HMU accumulates 2,000 hourssince-new, since-last-overhaul, or since-incorporation of Turbomeca Service Bulletin (SB) No ; or within 30 days after the effective date of this AD, whichever occurs later. (2) Thereafter, replace HMUs with a serviceable HMU at every 2,000 hours-since-new, sincelast-overhaul, or since-incorporation of Turbomeca SB No , whichever occurs later. (3) For the purposes of this AD, a serviceable HMU is an HMU fitted with a new constant delta P diaphragm in accordance with Turbomeca Service Bulletin No , dated October 18,
