Beryl D'Shannon Aviation is the headquarters for new and replacement propellers. With more than 40 years of selling props we have the experience to deliver the right propeller for the right application. Quality and safety are the first and last attributes in the Beryl D'Shannon name.

When it comes to propellers we associate ourselves with only the very best. Hartzell and McCauley Propeller Systems have a track record of delivering the same high standards that we maintain in our own products. BDS has always been on the front line as propeller designers bring forward the latest and greatest. We feel Hartzell's new scimitar design will follow in this tradition. In fact, so much so that we hold the only approved STC on this propeller.

Hartzell's Top Prop line has strong benefits in improved ground clearance and rate of climb, reduced noise and takeoff distance, longer overhaul intervals, a new propeller warranty, and increased safety and improved appearance. When converting from a two-blade propeller to a three-blade, takeoff and climb are generally improved while cruise speeds remain about the same. Two-blade to two-blade conversions are generally made to replace obsolete propellers, and performance would be unchanged across the flight envelope. A new generation of scimitar blade designs will deliver the best performance and lowest noise levels available.

New spinner assemblies are included in all Top Prop kits. The spinners are constructed of aluminum alloy, which is polished to a mirror finish. Generally the governors do not have to be replaced, however there are some installations such as early Cessna 180, 182 and Beech Bonanza models which do require a governor change. If a governor change is required, the proper governors will be listed on the STC documents.

Availability for Hartzell's Top Prop is always very good. The Top Prop line also currently covers over 120 different types of aircraft

TBO: For propellers installed on piston aircraft it is 6 years or 2,400 flight hours, which ever comes first. The only exceptions are agricultural aircraft, which have a 3-year/2,000 hour TBO due to the corrosive chemicals used with these aircraft.

Warranty: Top Prop propellers and spinners are warranted against defects in materials and workmanship for 1,000 hours or 3 years, which ever comes first. They also offer a 10 flight hour / 90 day full refund period if you are dissatisfied with the installation of the propeller on your aircraft.

McCauley's BlackMac line of propellers made its debut in 1989. A great design with innovative advancements in solid one-piece hubs, and internal steel split ring blade retention systems. A few improvements to look forward to depending on application are shorter take-off and landing distances in addition to a better climb. You will find significant noise reductions when installing three blade propellers vs. two blade propellers and when installing four blade propellers vs. three blade propellers. Oil filled hubs for piston aircraft are available which provide constant lubrication and corrosion protection. A design derived from McCauley's turbine propeller line. This system enjoys over twenty years of A/D free service excellence. No annual servicing is required beyond normal propeller care.

TBO: Piston applications are up to 2400 hours or 72 calendar months (whichever occurs first).

Warranty: Standard three year warranty on McCauley owned STC kits extended to include McCauley supplied replacement parts for components found unserviceable due to manufacturing defects at first recommended overhaul.
