VHM system Data to be analyzed M’ARMS - Analyze indicator MOD-45. IN CASE THE RED THRESHOLD IS EXCEEDED OR AN ALARM IS GENERATED, CONTACT THE EUROCOPTER HUMS SUPPORT BEFORE THE NEXT FLIGHT - Contact the HUMS Technical Support Department: Tel: +33 (0)4.42.85.99.25 Fax: + 33 (0)4.42.85.99.66. WebHUMS Application: https://keycopter.eurocopter.com - Calculate remaining flight time If the last acquisition was recorded within the last 30 minutes of the last flight, the duration of the next flight can be as defined above: duration of 3 hours maximum. If the last acquisition was recorded between 30 minutes and 2 flying hours ago, the flight duration since last acquisition must be deducted from the 3 hours authorized. If the last acquisition was recorded between 2 and 3 flying hours ago, perform a maintenance check flight of 40 minutes, in the above-mentioned acquisition condition. This maintenance check flight will be performed without passenger and over an area where an emergency landing on the ground within 10 minutes at Vy is possible. After the maintenance check flight, if no acquisition of vibration has been recorded, contact the EUROCOPTER HUMS support. If the last acquisition was recorded more than 3 flying hours ago, perform an eddy current inspection of the component, in the area of the weld, to make sure that there is no crack (according to paragraph 3.B.2), before the next flight. - Check alerts on the other indicators related to the main bevel gear area. CAUTION IN ORDER TO OBTAIN THE RECORDINGS REQUIRED FOR THE MONITORING OF MOD-45 OF THE COMPONENT “Bevel Shaft & Wheel”, THE ACQUISITION CONDITIONS REQUIRED BY THE M’ARMS MUST BE MET: - at Tq ≥ 60%. - at IAS ≥ 60 kt. <strong>EASB</strong> Revision 0 2012-06-27 Page 6/15 Revision 2 2012-11-21 This document is available on the internet: www.eurocopter.com/techpub
<strong>EASB</strong> 2) If you need to perform a flight of more than 3 flying hours and less than 10 flying hours, between 2 VHM data downloading operations, perform an Eddy current check of the component before flight, to make sure that there is no crack in the area of the weld according to paragraph 3.B.2. CAUTION ONLY LEVEL II AND LEVEL III OPERATORS CERTIFIED IN THE EDDY CURRENT DETECTION METHOD IN THE AERONAUTICS SECTOR ACCORDING TO THE EN4179 OR NAS410 STANDARD ARE AUTHORIZED TO CARRY OUT THE INSPECTION. MOREOVER, EACH OPERATOR HAS TO ATTEND AN ADDITIONAL TRAINING PERFORMED UNDER EUROCOPTER RESPONSIBILITY. THIS TRAINING WILL INCLUDE PRACTICING ON DEFECTS GENERATED ON REAL VERTICAL SHAFT AND ON REPRESENTATIVE COUPONS. NOTE 2 AS THIS SPECIFIC EDDY CURRENT PROCEDURE HAS BEEN VALIDATED BY THE EC QUALITY LABORATORY TO DETECT POSSIBLE CRACKS IN THIS PARTICULAR AREA, IT IS POSSIBLE TO USE THIS METHOD AS AN ADDITIONAL SAFETY BARRIER.
