Caution: Please Read Before Using This Guide

This document is NOT the FAA-approved Applicable Models List. Matters of certification eligibility can be found at www.hartzell.aero/pma.

 

This document is simply intended as a guide for fitting most aircraft by type. However, due to variances between aircraft due to manufacturing changes, modifications, cumulative years of maintenance and/or conversion, it is nearly impossible to definitively recommend the correct starter for any particular aircraft based on make/model alone. So please only use this document AS A GUIDE ONLY. When in doubt, contact Hartzell Engine Tech for confirmation. Installation of the wrong starter will void the factory warranty. Hartzell Engine Tech will not warranty starter wear or damage on starters (or engines) where a starter is installed incorrectly (including wrong ring gear teeth or wrong voltage, etc.) or is used in an inappropriate application.

 

There may still be a starter to fit an aircraft whose entry shows “no starter available”. Many older aircraft have been converted and upgraded. Confirm the engine make/model before determining a Sky-Tec is or is not applicable.

 

Please note the use of ring gear tooth count on Lycoming engines and aircraft voltage in the model numbers of all Sky-Tec starters. If your aircraft ring gear teeth and/or voltage do not match the numbers in the model recommended for your aircraft, DO NOT ORDER THE STARTER without first contacting Hartzell Engine Tech or adjusting your model number accordingly.

 

Recommendations are suggested for aircraft with factory standard equipment. Factory or after-market installed options such as air conditioning may affect the applicability of the primary recommendation. Piper singles with air conditioning must utilize the NL-series starters.

 

Please do not assume ring gear tooth count on Lycoming engines. Through the years, mechanics have been known to replace ring gears with different tooth models at the time work was performed. Therefore, it is imperative that the installer CONFIRM RING GEAR TOOTH COUNTS ON ALL LYCOMING INSTALLATIONS.

 

IF YOU ARE UNSURE WHETHER THE STARTER YOU RECEIVE IS CORRECT, PLEASE DO NOT MOUNT IT. Contact Hartzell Engine Tech first. Mounting the starter will preclude you from returning the starter to Hartzell Engine Tech as new/unused. Mounting the starter places “bite witness marks” around the mounting holes and will have to be treated as a used starter. No new exchange will be permitted.

 

Never use a PM or LS (permanent magnet) starter on a helicopter. Hartzell Engine Tech recommends ONLY  HT or inline starters (NL models) for use on helicopters.

 

And finally, this list is only as comprehensive as we could attempt to make it. We realize there are omissions and variances. We’ve done our best to include the majority of general aviation aircraft models. If you cannot find what you are looking for (or what you are looking for is not where you’d expect it), we encourage you to contact Hartzell Engine Tech to find the best starter for your particular application.
