6April 2016Welcome MeTRO/MeRLIN Operators!Troy BeshearsDirector of SparesHello 2016, in true Elbit SystemsAmerica fashion, we hit the groundrunning. As last year closed I wasproud of the progress the organizationmade to better our processes inmeeting customer demands. Everynew year our senior leadership teamprovides guidance on the area’sthey want to see us improve andgrow. There was much discussionabout the Spare’s business and ourcommitment to our customers.We were challenged to focus onarea’s that impact our customersmost. After reviewing the last fiveyears of sales for all customers,we identified 1,098 parts that werebought four or more of those years.These are considered our priorityparts. We engaged with our SupplyChain Management (SCM) team toset goals that include; minimizingre-stocking delays, reduce partcosts and improve on time delivery.To that end, our SCM team wassuccessful in realizing cost savingson 17% of the priority parts weidentified, which will be passed onto our customers. We would like topublicly recognize Sharon Vidaurriand her team for their hard work.We would be remiss if we did notacknowledge all the hard work anddedication to customer satisfactionour Tech Support Personnel andEngineering Department provide.We know that Mark Provost and histeam continually seek opportunitiesto make improvements to the aircraftthat will improve functionality,maintainability and sustainability.This will be another year of challengesas we continue our path to sustainedcustomer satisfaction and after nearlya year in this position, I am lookingforward to hitting the road and visitingas many of your organizations as I can.We at Services & Support Solutionsare dedicated to supporting theMetro/Merlin Fleet and will continueto strive for improvements in thatsupport. See you at the 2016 Metro/Merlin Operators Conference.Sincerely,Troy BeshearsHello MeTRO/MeRLIN Operators,Glen WibrachtManager of Spares SalesHere we are with the first edition ofthe Metro Global for 2016. Several ofus here at Elbit Systems San Antoniohave been working on the new Metro/Merlin spare parts price book. Ibelieve I had mentioned earlier thatthese published prices will remainvalid throughout the year of 2016,and we are very close to releasingthe 2016 version. In this edition, wewill list those items that we see thatare the most frequently used parts,with future editions that will containa lot more part numbers. It has beenmany years since a price book forthe Metro/Merlin spares support hasbeen issued and this will be the firstprice book released by Elbit SystemsSan Antonio in support of the Metro/Merlin Aircraft. We look forward toworking with everyone, and we thankyou for your continued support.Sincerely,Glen Wibracht

8April 2016AD 2016-04-04 Ref. Airplane Flight ManuaLThe FAA has adopted a new AirworthinessDirective (AD 2016-04-04) for M7Aerospace LLC aircraft models (seeAircraft Models below). The AD wasprompted by a report of an accidentwhere an M7 Aerospace Model SA227AC airplane experienced left enginepower loss and consequent loss ofcontrol. Training manuals providedescriptions of the Negative TorqueSystem (NTS), which provides anti-dragprotection if a negative torque condition issensed. This feature might cause pilotsto assume the system automaticallyAIRCRAFT 6–TCSA227–TTSA227–AC (C-26A)SA227–ATSA227–BC (C-26A)SA227–CCSA227–DC (C-26B)REF: AIRPLANE FLIGHT MANUAL (AFM)provides full anti-drag protection in theevent of an engine failure or power loss.The pilot must also take prompt actionto fully feather the propeller on thefailed engine to reduce drag. A pilot’ssole reliance on the NTS for reducingdrag in the event of engine powerloss may result in the pilot’s failure toinitiate the Engine In-flight checklistand feather the propellers in time.This AD requires inserting updatesinto the Airplane Flight Manual (AFM)and/or the Pilot Operating Handbook(POH) that will clearly establishthat the NTS is not designed toautomatically feather the propellerbut only to provide drag protection.Effective Date/ Contact:This AD isAIRCRAFTMODELSeffective April 8, 2016.

Vol 34 / No 1Reduced Power Takeoff TipSome of the important things to considerwhile operating your aircraft are waysto get the most out of your fleet’sperformance. Using only required powerfor take off, cruise, and climb will havea lasting positive effect upon overallengine health. It is not necessary to use100% torque and 650 Exhaust GasTemperature (EGT) when more thanadequate performance is achievableat substantially reduced powersettings. The airplane flight manual(AFM) provides information on how todetermine the minimum power requiredfor take off. On some aircraft models,adjustable “bugs”, are available for thetorque indicators as a handy meansof setting the required reference.Moisture IN Flight Instrument Static PortsWe have received reports of moistureentering the instrument static system; itappears the moisture is entering the staticvents, particularly during heavy, rainyweather when the aircraft are parkedoutside. In the past we have had a fewsporadic reports of similar, but not thesame type moisture contamination. Inthose cases, the operator(s) attributedthe moisture collection to high humiditycontent for long periods or in somecases strong rains. These operatorsdrained the static system and nofurther occurrences were reported.In anticipation of a possible repeat of thiscondition, Service Bulletins SA227-34-008and CC7-34-005 published in 1996, alloweasier access to the drains by extendingthe drain ports and locating them in theCargo Compartment area. This promoteseasier access plus frequent draining of thesystem minimizing recurring problems.M7 Aerospace does not offer, as groundsupport equipment, moisture guards toinstall on the Metro static ports. A quickresearch in the Internet lists commercialcompanies that offer such guards andappear to be reasonably priced. It shouldbe noted that the 4 Flight Instrumentstatic ports located on either side of thefuselage, aft of the Cargo Door area, arethe most sensitive and are quick to indicateproblems since the Flight Instrumentsare constantly monitored by the crew.Nevertheless, there are a total of 9 staticports connected to other systems (CabinDump Valve, Pressurization controls,etc.) that should also be considered,especially if operating in and aroundheavy precipitation or if problems inthese areas are attributed to moistureentering those systems’ static ports.If any other operators are havingor have had similar occurrences ofmoisture contamination, please provideM7 Aerospace with details such as:1. System(s) affected.2. Manner of symptoms noteand corrective action.3. Amount and frequencyof contamination.4. Other type of contamination.5. Compliance with Service Bulletinscited and effectiveness on system.6. List type of operating environment/conditions where most affected.7. Any other unusual like discrepancies.If you have any comments/detailsto share, please send them to:MetroTech@M7Aerospace.com9
10April 2016JACKING AND TOWING PRECAUTIONSThe following precautions and practicesshould be observed when jacking theMerlin / Metro aircraft. Failure to adhereto these practices and proceduresmay result in damage to the aircraft orinjury to personnel. Figure of jackedaircraft is shown on page 11.PROCEDURES:1. As a safety precaution whentowing the aircraft for extendeddistances or across active taxiwaysand runways, station a qualifiedperson in the pilot seat to man thebrakes in case of an emergency.PRECAUTIONS:1. Jacking the aircraft outside of ahanger is NOT recommended.2. Station observers by eachwing tip and by the tail toverify obstacles clearance.2. The aircraft should be on a hard,level surface when jacking.3. Verify that all three landinggear drag braces are in overcenter locked position.3. Loose cargo, tools, and equipmentshould be removed from theaircraft before jacking.4. ALL three jack points MUST beused and jacks raised smoothly andevenly during jacking operations.5. When one or both engines are removed,provide adequate tail support andbalance to maintain aircraft balance.PRACTICES:1. The aircraft is jacked at three pointsfor all wheel, tire, brake and landinggear maintenance that requirestransferring the aircraft weight fromany of the three landing gears.2. Raise jacks simultaneously tomaintain aircraft in a level attitude.3. Place a support under the aft fuselage.4. When lowering the aircraft, lower allthree jacks simultaneously to maintainthe aircraft in a level attitude.TOWING:Because of the direction in whichloads are applied during taxiing, thenose wheel steering is allowed todeflect the nose wheels an additional13 degrees past the towing turnlimits, to a maximum of 63 degrees.4. Close all aircraft doors.5. Tow at low speeds andavoid jerky movements.6. Move the aircraft in a straightline before turning.7. Observe turning limits markedon the nose strut.CAUTION– DO NOT TOW AIRCRAFT WITHNOSE WHEEL ARMED ANDBATTERIES ON. DAMAGE TOTHE NOSE WHEEL STEERINGACTUATOR CYLINDERSIS PROBABLE.– DAMAGE WILL OCCUR TO THENOSE WHEEL CENTERING CAMAND CAM FOLLOWER IF THETURN LIMITS ARE EXCEEDED.

12April 2016Proper Lubrication TipsLubrication of aircraft components isusually a messy task, but an importantnecessity. As with any job, in orderfor it to be effective it must be donecorrectly. Some things to keep inmind when lubricating components:1. Use the right lubricant for the job.Using the wrong lubricant cancause problems. For example:A high temperature lubricantmay not have a sufficient lowtemperature range and could freezeat altitude or in cold weather. Thiscould be disastrous if applied toflight controls. Conversely, a lowtemperature grease applied to wheelbearings may sling out on the firstlanding causing bearing failure.When in doubt check Chapter 12of the Maintenance Manual.2. Zerk fittings are not the onlylubrication points. Do not neglectbearings and rollers. Application oflubricants with a squirt can or brushis a necessary part of the job.3. NEVER USE PRESSURE CAN“LUBRICANTS” SUCH AS LPS ORWD-40. These are not lubricants,but solvents designed to loosen“frozen” or rusted parts. Once thepart is loosened, the appropriatelubricant should be applied.Where parts are being simplyrelubricated, the proper lubricantsshould be added with a squirtREMEMBERSMOOTH OPERATIONOF THE LANDING GEARAND FLIGHT CONTROLSDEPENDS ON PROPERLUBRICATION OF THEIRCOMPONENTS.can or brush. The solvents willsimply wash out any remaininglubricant and accelerate wear.4. Avoid the use of pneumatic greaseguns. While they may speed thejob up they may cause failure ofbushings that have no relief holes.5. If after several attempts youare unable to get a zerk fittingto accept grease, remove thefitting and clean it out. If thezerk still refuses to cooperatethen the component needs tobe taken apart and cleaned. If itdidn’t take lube from you it mayhave been missed the last timeand could be wearing rapidly.6. Remove excess grease and oil witha rag when you are through. Lefton surfaces, grease and oil attractdirt and grit which ends up on otherparts of the aircraft once airborne.For questions or comments, pleasee-mail: MetroTech@M7Aerospace.comNEW FAA MMEL FOR SA226/227 Revision 16BThere is an update on the MMEL for the SA226/227 Series aircraft by the FAA on January20, 2016.

Vol 34 / No 1Metro Training ServiceElbit Systems of America / M7 Aerospacehas provided Metro Training Servicessince 1993. We have organized a teamof knowledgeable and experiencedtechnicians and illustrators to designand implement training for all Fairchildmanufactured Merlin and Metro aircraft.Our concept, learning Type Aircraft Systems,is much like learning Mathematics; thereseems to be a true and logical sequenceof functions that need to be learned for theprocess to be effective. For example: Onedoes not learn multiplication without firstlearning addition and subtraction. One alsodoes not learn Algebra without first learningmultiplication and division and so on.To apply this concept, we designed ourcourses to start with a General section thatprovides the student with an overview ofhow the aircraft is manufactured/assembled,describing some of the basic structuresand assemblies that form the aircraft.Electrical components is the next choicein the sequence due to the substantialamount of components and systemsprovided by the aircraft.
