EASA SIB No.: 2018-05 Safety Information Bulletin Airworthiness – Operations SIB No.: 2018-05 Issued: 08 February 2018 Subject: Multi-Purpose Flight Recorders Ref. Publications: Penny & Giles Aerospace Limited Service Bulletin (SB) No. D51615-31-22, dated Feb 2018. Applicability: Penny & Giles multi-purpose flight recorders (MPFRs), as listed in the effectivity of SB No. D51615-31-22, a copy of which is attached to the record of this SIB on the EASA SP Tool. Description: During data recovery from crash-damaged MPFRs, previously installed on five helicopters involved in accidents where the aircraft was submerged in water, corrosion was detected on the pins of memory devices inside the recorder. To recover the data, these units required the use of special techniques, not permitted according to the Minimum Operational Performance Specifications of the relevant ETSO, which delayed the availability of data to accident investigation boards. This type of corrosion is due to a chemical reaction between the fire insulation material, when partially dissolved in water, and the iron content within the pins of the memory device. Under certain circumstances, the conformal coating on the memory module can be insufficient to protect the device pins from the corrosive solution. This issue potentially affects certain second generation “GEN2” memory modules installed on MPFRs manufactured between 06 April 2006 and 02 January 2013. The subsequent GEN3 memory modules use a different conformal coating process and are protected from corrosion. At this time, the safety concern described in this SIB is not considered to be an unsafe condition that would warrant Airworthiness Directive (AD) action under Regulation (EU) 748/2012, Part 21.A.3B, nor the issuance of an operational directive under Regulation (EU) 965/2012, Annex II, ARO.GEN.135(c). Recommendation(s): EASA recommends owners and operators to accomplish the actions as specified in Penny & Gilles Aerospace Limited SB No. D51615-31-22 dated Feb 2018. This is information only.

Applicability This Service Bulletin is applicable to the following Multi-Purpose Flight Recorder (MPFR) Type: 051615-102, See Table 1 for effectivity This Service Bulletin only applies to units with an ETSO listed in Table 1. This Service Bulletin does not cover units that may be affected outside the serial number ranges specified in Table 2. Reason During crash damaged data recovery of MPFRs installed on five helicopters involved in accidents when the aircraft were submerged in water, corrosion was detected on the pins of memory gevices inside the recorder. These units required "special techniques" to recover the data, which are not permitted in the Minimum Operational Performance Specifications (MOPS). The corrosion is due to a chemical reaction - between the fire insulation material, when partially dissolved in water, and the iron content within the pins of the memory device. The conformal coating on the memory module can, under certain circumstances, be insufficient to protect the device pins from the corrosive solution. This problem has been isolated to the second generation "GEN2" memory modules fitted to the MPFR. The subsequent GEN3 memory modules use a different conformal coating process and are protected from corrosion. The corrective action requires these GEN2 memory modules fitted to MPFR recorders to be replaced with the GEN3 version. 2. General Data retrieval from MPFRs fitted with GEN2 memory recovered from accidents involving water submersion has been 100% successful. Furthermore, additional testing and analysis has been performed to develop data recovery methods using special techniques that involve removal of memory devices from the printed circuit Date: Feb2018 051615-31-22 Page 1 of 6  Penny & Giles Aerospace Limited 15 Enterprise Way Aviation Park West Bournemouth International Airport Dorset BH23 6HH United Kinadom board and if necessary disassembly of the memory device itself to read out the recorded data. Penny & Giles Aerospace Ltd will work with the operator to schedule the upgrade of the GEN2 crash protected memory module in the affected serial number range at the earliest opportunity in the following circumstances:- • During the 72-month mandatory maintenance check as detailed in the Component Maintenance Manual (CMM) 31-34-22 and Product Instruction Manual (PIM422-1). • Within the next aircraft major maintenance cycle effective from April 2019 onwards. • Any units currently not installed in aircraft shall only be installed after the unit has been upgraded to GEN3 . • Alternatively, it will be incorporated in any unit that has been sent in for general repair or upgrade. More information regarding data recovery using special techniques is available in the Crash Damaged Recovery Equipment Operating Manual PIM456-0 November 2017 , which can be obtained from the manufacturer see "Contact Information" further below. 3. Approval Issued by Penny & Giles Aerospace Limited under the terms of the Company's international Quality Approvals. 4. Manpower Not applicable. 5. Material. Cost and Availability Direct costs to replace GEN2 memory modules with GEN3 will be covered by Penny & Giles Aerospace Ltd. 6. Tooling. Price and Availability Not applicable. 7. Weight and Balance Not affected.
