Introduction to Trouble Shooting

Tip Charts It

In preparation of the following H tip charts l two basic assumptions are made t the flight crew has followed the correct operating procedure and (2) the problem is caused by a single failure or malfunction

Each chart is organized in five sections situation~ conditions cockpit indications ntost probable area and probable causes

The Situation is the main point of the problem as Isquawked by the flight crew

The Conditione are the characteristics ot the selected engine operation at the time ~ation

The Cockpit Indications are those indications which ntuet be noted at the time the situation occurs in order to fully define the problem and thereby make one specific chart appUcable These indications are necessary to select the optimum starting point for trouble shooting

The Most Probable Area is the area (engine propellerraquo or aircraft and QEC) which contain components most applicable to the problem

The Probable Causes include the components in each area which can possishybly cause the problem

Each tip chart II is applicable to a specific type of problem There will be situations encountered for which there is no applicable chart but the methods and principles used on the Htip charts1 are effective in all maintenance problems

The 1tip chart811 will be effective if certain basic rules are observed

1 Obtain as much information as possible from the flight crew and their write-up In many cases this information will define the problem comshypletely and eliminate the need for an engine run-up

2 Use the tip chart a check list and follow the numerical Qrder of the chart down to the Moat Probable Area Make special note of each coekpit indication in order to avoid uaing a tip chartgt which is not applicable to the problem

3 ProcHd to the section under Probable Causee which correeponds to the area liated under Most Probable Area On mOlt 01 the tip charts a brief discussion or the cockpit indications i8 included to e~lain the reasoning ueed in selecting the Most Probable Area If investigation ot the most probable area reveals no abnormal conditions proceed to the other two areas

4 When checking a given component be aure to read all applicable tootshynotee

Aa 118 true with any trouble shooting information these charts are dependent upon the engine and aircralt indicatinc eystems and therefore caution must be exerciaed to avoid trouble ahooting difUcuHiea cauaed by lalse indications In most casel a false indication may be detected by checki it against the other indicationa for that englne For example a TIT indiCating aystem malfunction ahould be euapeeted It the TIT ie bigh low or cycling with no change in fuel flow andor horaepuwer In the case of the primary Cuel pump failure light whlch is used to indicate fuel pump paralleling on a start the prelsure switch setting may shift and not energite the light when the pumpI are operatinc in parallel the pump pertormance may be Sluggish or the paralleliti valve may mtJfuncHon

For this reason the Ught may be relied upon only if it comes ON between 2200 and 9000 RPM definitely indicatinc normal parallel pump operiHion l the light is OFF it may be any one ot the above malfunction Similarly the fuel boost pump pressure light is reliable only if it is OFF If the light i8 ON indicating that the pressure riee aCTOBS the engine driven boost pump is below the 18 psi lImit the reason may be a pressure switch letting shifL

The ollowrni abbreviations and symbols are used in the tip chartl
