Factory repair or factory issued replacement of any starter Sky-Tec determines has failed under the terms of this warranty if and only if the original starter is sent to Sky-Tec for evaluation. 

Labor to Remove & Replace the starter;

Damage to any other engine or aircraft components or any non-starter-related expense(s);

Compensation for the cost any starter purchased from any third party, agent or distributor besides Sky-Tec to replace any failed starter;

Starters used in any improper application;

Starters improperly installed. Ring gear/starter mismatches are the sole responsibility of the installing mechanic and/or aircraft owner;

Starters serviced in the field by removing or replacing any components not specifically instructed and/or supplied by Sky-Tec;

Starters determined to have failed by application of voltage in excess of amount specified on starter name plate (physical evidence: armature will be splayed and/or exploded due to the forces of over-rotation and the associated centripetal force WITHOUT discoloration of commutator bars or heat warping of brush insulator);

Starters determined to have failed by application of voltage in excess of cranking time specified on the starter tag that ships with all starters (physical evidence: copper armature bars discolored to white/purple hues, brush wires are discolored similarly, brush insulator is warped or scorched, smell of burnt metal evident, etc.);

Starters determined to have failed by a counter-rotational force caused by the engine’s ignition system failing to retard all sparks at or past piston TDC during the cranking period aka “kickback” (physical evidence: bent or broken mount, broken or displaced magnets, broken or chipped brush assemblies, broken drive components and/or excessively worn or damaged drive gear teeth);

Starters containing any foreign substance or debris including motor oil, cleaning agents or foreign particles not found in the starter’s normal composition (physical evidence: presence of substance within starter causing solenoids or motor brush assemblies to wear prematurely and/or function improperly);

Starters within specifications that operate normally (i.e. the starter is good). Warranty applies to starters with defects, not good starters. Starter will be returned to customer.  If refused, core credit may be given to the customer should the core be determined to be rebuildable at Sky-Tec’s sole discretion; or

Starters damaged by impact, shock, excessive shaking or other physical abuse (physical evidence: dents to starter components, loose or stripped connection terminals, and bent components not caused by defects in components, design or workmanship). 

Sky-Tec does NOT warrant damage to non-starter components or any non-starter-related expense(s) including labor, inconvenience, transportation or loss of business due to any starter failure.

Warranty does not cover normal shearing of NL and ST2 model starter kickback protection shear pins. Shear pin repairs are to be performed in the field.

Warranty does cover any NL or ST2 model starter that becomes damaged should a kickback protection shear pin fail to shear. 

The NL starter is designed to fit nearly every Lycoming aircraft application by simulating the location of various mounting points found on the old, heavy OEM starters. As such, NL starters feature four machined aluminum bosses cast into the starter mount. These bosses are not required for proper function of the NL starter but serve only to support accessories on/around the starter. If a specific aircraft installation requires the alteration or removal of one or all four of these bosses, customers may remove the bosses without loss of any warranty privileges. Acceptable means of removal include cutting and/or grinding without incurring any damage to other starter components or features. However, starter damage or starter failure due to the improper or inappropriate removal of these bosses will not be covered under the factory warranty.
