Someyearsago,wheninCypruswiththeArmy,I cameacrossastrangeandheavy-lookingtraining aeroplaneoutsideagarageinLimassol.Itwasthe onlyYakIIIhadeverseenandwasapparentlybeing deliveredfromCzechoslovakiatoEgypt,whenitwas obligedtodiverttoCyprusandmakeaforced landing,whichcausedquitealotofdamagetothe airframe,andespeciallythepropeller.

TheYakwasoneofaseriesofdesignsusedfor primaryandadvancedtrainingintheSoviet countriesand,apartfromtheEgyptianexamples,I canfindreferenceonlytoasmallnumberusedin Austriaduringthe1950s.TheTypeIIwasapparently theheaviestoftheseriesandresembledtheNorth AmericanHarvardingeneraloutline,buthadmuch lesswingareaandanadditional150hp.intheradial motor,whichgaveitaverybusinesslikeandnotvery forgivingappearance.

ThisYakwasveryexpertlyrebuiltbyspecialistMr. Doug.BianchiofHighWycombe,andhehadonly thebarestofinformationtoworkfrom,aspartswere quiteunobtainableandtheRussianswouldnoteven admittohishavingtheaeroplane,farlessprovide data.Hisstoryofobtaining2propellerbladesfrom anundisclosedmilitarysourceinaneasterncountry makesinterestingreadinginitsownrightand,no doubt,suchthingsarenotcomebycheaplyor withouthazard.

MuchdesignseemsborrowedfromtheHarvard, aspanelsdetachedfromthefuselagesideandunder thewingsforveryeasyaccesstothesystemsandthe wholeaeroplanewasveryruggedandwellplanned. TheairintakehadthecharacteristicRussianaperture foundinmanycameras,adjustableforverycold conditions,theflapswereoperatedbycompressed air,likemostservicesandwereeitherupordown, andnotverystronglymade.Anemptymachine-gun bayinthewingwascoveredoverandfurther inspectionprovedthattheenginewasquite conventional,butdroveanaircompressortocharge areservoir,uponwhichdependedtheundercarriage andbrakes,inadditiontotheflaps.Incaseof failure,anemergencyreservoircouldbeselectedand youhopeditlasteduntilthelandingwascomplete!

Theinteriorwaswellarranged,withgoodstrong controlsandplentyofspace,veryliketheHarvard andstartingprocedureswerealmostidentical,apart fromtherathernoisyplumbingwhichcarriedtheair supply.TonyTrowbridgeadmittedthattheYakwas stillsomethingofanunknownquantityandwewere luckythatChampionAerobaticpilotNeilWilliams hadbeenabletoflyaYakvariantinMoscowin 1968,ashisexperiencewasdrawnuponheavily.

Thusourfirsttake-offwastheclassic'short' variety,withmuchpowerapplied,beforereleasing thebrakes,movingquicklytoaflyingattitude,much rudder,or,Ishouldsay,ALLtherudderneededin theprocess.Theaccelerationwasfrighteningandthe Yakmissilethundereddowntherunway,which seemedalmostcompletelyusedupbeforeiteven thoughtofleavingtheground.Infact,itflewat 85kts.,veryunresponsiveatthatspeedandbecame manageableat120kts.,thenearestthingtoa recommendedclimbingspeed.HighWycombewas certainlynottheplacetotrainonthisaeroplaneand anydifficultyatallduringtake-offwouldleadsurely toanaccident.However,wewereintheairand almostimmediatelyfoundthatthehighpowersetting stilldidnotchargetheairreservoirenoughtoretract theheavy,wideundercarriage.Theredstalks remainedobstinatelyinthe'partiallyextended' positionoutonthewings,thusourspeedwaslimited to120kts.untilweworkedupenoughpressure.The leaksunfortunatelyoutpacedthecompressorandthe decisionwasmadetoland,makinguseofthe emergencyreservoir.Theflaps,whichwentdown acceptably,drainedthereservoirgreatly,the undercarriageneedingverylittleair,asitsweighthad takenitalmosttothedownposition,whereitlocked, toourintenserelief.

Thisleftthelanding,fromacircuitinwhichquite largeanglesofbankwererequiredtokeepthe airfieldinsight.Despitethelowairspeedbeing usedtheapproachwasnecessarilycurved,asitwas verydifficulttoseeclearlyahead,comparedwith mostlightaeroplanes.Wesweptdowntothethreshholdreducingspeedfrom120kts.,theYakfloated onlybrieflyandwasonthegroundwiththestick hardback,stillmovingveryfast.Theairfieldpassed atahorrifyingrate,thebrakesbeingusedasfaras possibletostopbeforegoingontothemotorwayat theoppositeend!Wemanagedit,butonlyjust,using alltherunwayandapartofthecurvedtaxi-way beforecomingtoastandstill,theemergencycylinder completelyexhausted.Fortunately,therudderwas fairlyeffectiveatlowspeeds,butthiswascertainly notabeginner'saeroplaneandanytrainingonone wouldrequireagreatdealofspace,whichtheysurely haveinRussia!
