ISSUE 2 OF SPECIAL CONDITION EVTOL ⏩️The main point in my view is the extension of the maximum certified take-off mass to 5700kg instead of 3175 kg, the max passenger seating capacity remains to 9. This mass increase will allow more flexibility for designers. ⏩️Another significant change is the introduction of requirements for Electrical Wiring Interconnection Systems (EWIS). ⏩️It should be noted that two requirements have been modified to reflect EASA and FAA harmonisation work: VTOL.2105 (b) (1) on accounting for vertiport altitude in performance data and VTOL.2205 (c) on accounting for single failure. Further alignments are expected in the short term. Other changes are about: ⏩️Installation of recorders ⏩️Limited overwater operation for consistency with 2024/1111 (Piloted Innovative Air Mobility Operations) ⏩️Replacement of VMO and MMO by design speeds based on CS27/29 ( small/ large rotorcraft) ⏩️Consistency of safety objectives between VTOL.2240, 2440 and 2510 respectively structural durability, lift/ thrust system fire protection and equipment and system installation. ⏩️Naming consistency with 2024/1111 Read more at https://lnkd.in/ezpEQmVg

The Proposed #Airworthiness Directive ( PAD ) affects bearing No.3 spring finger housing, having Part Number 2629M62G01. It has been determined that affected parts, when installed on #CFM #LEAP-1A engines, may be subject to accelerated wear, which could lead to elevated non-synchronous vibrations ( NSV ) during engine operation. This condition, if not detected and corrected, may induce #engine #stalls, or result in secondary air system seal rubs, cooling airflow reduction, or elevated temperatures in turbine internal cavities, all which could lead to HPT disc failures, possibly resulting in release of high energy debris with consequent damage to, and reduced control of, the #aeroplane. To address this potential unsafe condition, #CFM published SB LEAP-1A-72-00-0504-01A-930A-D with a list of the affected parts. The PAD would give operators of affected #Airbus #A320neo-family #aircraft 125 cycles to calculate NSV data and repeat the process every 125 cycles. If certain CFM-specified thresholds are exceeded, the #bearing must be changed. This PAD would also require, following the removal and replacement of the No. 3 bearing spring finger housing, inspection of the stage 2 HPT nozzle assembly honeycomb and HPT stator stationary seal honeycomb for rubs and, depending on findings, replacement of the stage 2 HPT nozzle assembly honeycomb and HPT stator stationary seal. In addition, it would mandate swapping the bearing out before the engine reaches 9,900 cycles. #ENGINEMRO #MRO #OEM #GE #LEAP1A #AVIATION #aviationnews #FAA #EASA #AIRWORTHINESSDIRECTIVE #ENGINEFAILURE #MTBR #airlines #shopvisits

The RG-24-10 General aviation battery designed for a two battery, two bus, two alternator / generator system to satisfy the requirement for a secondary system to support FADEC and / or Glass Panel installations. Designed to run in parallel only when cranking. These are the only batteries required in the aircraft. Emergency Battery for lighting, standby, back up power, avionics and FADEC. Protects and extends the life of other avionics. Concorde\'s Emergency Batteries float directly on the DC buss with no need for a dedicated charger. This results in a high inrush current which extends battery life with fast recovery time from discharge. With the battery floating directly on the buss, transient spikes in the DC power are absorbed. These batteries are self regulating on charge and will take only the current required to maintain it at full charge. FEATURES: -Voltage: 24V -Rated Capacity C1: 8.5 AH -TSO Authorized: No -Full Authority Digital Engine Control (FADEC) -Electronic Engine Control (EEC) -Electronic Flight Instrument System (EFIS) and / or -Electronic Ignition Systems -Recombinant Gas - The RG® Series are low resistance, valve regulated lead acid (VRLA) batteries. -Factory tested to assure airworthiness -Shipped fully charged and ready to install -Manufactured with absorbed glass mat separators (AGM) -RG® Series batteries ship Hazmat EXEMPT via land, sea or air BENEFITS: -Superior starting power -Aerobatic: Non spillable at any altitude or attitude -Constructed with non removable vent valves - no addition of electrolyte or water required -Low impedance design. In stock and ready to ship Contact us today. 𝘼𝙚𝙧𝙤𝘾𝙊𝙍𝙀 - 𝙆𝙚𝙚𝙥 𝙊𝙣 𝙁𝙡𝙮𝙞𝙣𝙜! ---✈ #concorde #Efficiency #Durability #TopChoice #Aerocore #aircraft #aircraftmaintenance #avionics

"The aircraft was being flown by a remote pilot on a test flight at 30 ft agl when a propeller blade detached from the electric propulsion unit 3 forward motor due to a failure of the adhesive bond between the propeller blade sheath and spar. Large out-of-balance loads generated by the blade release caused structural failure of the right inboard pylon, resulting in damage to the aircraft’s wiring harnesses. This caused a loss of thrust from motors 4 and 7. Whilst the aircraft’s flight control system was able to maintain a level attitude, the high rate of descent caused by the loss of vertical thrust resulted in substantial damage to the aircraft when it struck the ground. The aircraft manufacturer was, at the time of the accident, in the process of introducing a blade design that, amongst other things, eliminated the bonding failure mode that caused the blade release. The manufacturer’s investigation identified 36 product and process improvements resulting from findings of the investigation." https://lnkd.in/dvvpBJ5Y #flightsaferty #aviationsafety #airworthiness #certification

Convert your FAA Instrument rating to Transport Canada. I have many pilots each week completing their exam conversions with me :) See the link in the comments section

IGNITION FAULT DURING ENGINE START IS NOT ALWAYS BECAUSE OF IGNITION SYSTEM DEFECTS AND SOMETIMES OCCURS DUE TO FUEL NOZZLES BLOCKAGE, NOT PROPER PROPAGATION OF FUEL INSIDE COMBUSTION CHAMBER AND ENGINE LIGHT OFF LOGIC INSIDE ECU ON CFM56-5A, AT ENGINE START, THE ECU COMMANDS IGNITION A(B) ON AT 16 PCT N2. THE HP FUEL SHUT-OFF VALVE IS OPENED AT 22 PCT N2. THE IGNITION FAULT WILL BE SET IF THE ENGINE IS NOT LIGHT OFF AFTER 18 SEC FOR OAT HIGHER THAN 34 DEG C, RESPECTIVELY 27 SEC FOR OAT BELOW 34 DEG C DURING THE FIRST START ATTEMPT. AT THE SECOND ATTEMPT THE FAULT WILL BE SET AT RESPECTIVELY 13 SEC AND 22 SEC. #a320 #maintenancemanager #aircraftmaintenance #troubleshooting #airbus #CFM56 #CFM56-5A #IGNITION

Very valuable lessons learned here for all AAM manufacturers. Quality, change management/configuration management, Airworthiness and design need to go hand-in-hand to be able to deliver succesful flight testing. There is no room for "quick changes" there...

SME with 30 years of leadership in avionics, solid rocket motors, ordinance, and mechanical systems for rocket systems.
https://lnkd.in/gcA68MgM it Is Interesting that the valvetech and aerojet dispute is out In the open. there uas been chatter about this. valves, In general, have always been challenging, so many known and often seen failure modes. it. is easy to say that these critical parts "meet requirements" but i would suggest they look at if the workmanship screening tests were adequate and exceed "test like you fly" AND "fly like you test" requirements, always.

The most commonly used 24V portable power supply, this START PAC® model has been designed to power up 24 Volt aircraft systems and will continuously deliver up to full 50 amp DC output. The voltage output is set to 28.5 Volts to simulate the same voltage as when the aircraft is running under power.
