Hartzell extends Top Prop warranty

Cranking and cranking an engine slow to start without taking time between turns of the key will destroy a starter. That is the topic of the first in a series of educational videos produced by the market leader in general aviation aircraft engine accessories, including starters, turbochargers, and fuel pumps.

Hartzell Engine Technologies President Mike Disbrow announced the new video series at EAA AirVenture, with a video that covers tips for extending the life of a starter by allowing the starter to cool off between cranks. Duty cycle requirements vary by model, but typically involve limits of 10 seconds of cranking followed by at least 20 seconds of rest, and limiting start attempts to 20 (or fewer) before a 10-minute cool-down period.

Disbrow made a variety of other announcements and updates, details of which also were posted on the company website.

Disbrow’s firm is owned by the same holding company that owns the famous propeller maker. Hartzell Propeller announced July 24 an extension of the warranty period for its line of Top Prop conversion propellers. The longest warranty in the industry, previously limited at three years or 1,000 hours, the Top Prop warranty now covers those propellers all the way to overhaul.
