General Information

Development for this conversion was a 4-year process in which Aircraft Performance Modifications was granted the STC as well as its PMA. Flight Testing was provided by High Altitude Aircraft Solutions where results yielded a 4 - 7% increase in airspeed. Located on the under-surface and aft of the pressurized bulkhead, APM's Aft Body  Strake Conversion reduces drag by creating an area of increased pressure under the empennage thereby reducing the amount of drag the empannage incurs during flight.


Fly With Peace Of Mind

As with all pilots, safety is the No. 1 priority. With an increased safety margin in emergency engine failure, you'll be flying with the peace of mind that your aircraft has better response and improved stability in single-engine operation. 


Streamlined Airflow Yields Results

Pilots notice right after lift off just how much of a difference the strakes make. Not only do the strakes lower the aircraft's stall speed by a few knots, but they also significantly improve yaw stability. Additionally, you'll notice that with the strake conversion your aircraft's rate of climb has improved as well. As soon as your 400 series Cessna reaches cruising altitude the improvement in airflow that the strakes provide do all the work for you. With the reduction in drag we're confident you'll be pleased when you arrive at your destination earlier, with more fuel on board and money having been saved!
