Experience and Innovation In Howell’s H9900 Series

Answering an industry demand for a heightened focus on efficiency, Howell’s H9900 Series of indicators carry minimal installation costs with a superior degree of quality and accuracy.

Designed for launch customer Blackhawk Modifications, Inc., the H9900 Series Indicators feature an innovative modular design, enabling multiple applications with a few application-specific dial face and software configuration changes, making them relatively easy to certify. Hardware consistency throughout different indicators creates an entirely new functionality with nominal redesign and recertification, maximizing adaptability, flexibility and expandability.

Howell’s Director of Field Engineering, Bill Milton comments, “Our core competencies have always hinged on listening to specific market needs and designing accurate, quality products with low or minimized installation cost to keep the aircraft flying longer. Understanding that installation has an associated cost that is often more than the hardware, we can offer ‘plug and play’ solutions.”

The first units were delivered in June of 2014 and to date, over 100 units have been delivered. Within 12 months, 31 part numbers have received Technical Standard Order (TSO) Authorizations. Currently, H9900 applications exist for 17 different aircraft versions and different types of engines including, Cessna Caravan 208, Cessna Conquest, King Air 90 Series, King Air 200 Series and the Cheyenne Piper, among others.

An essential feature of the H9900 Indicators is the digital bus that allows for system expansion. These indicators provide a practical gateway to a modular system that will offer real solutions for aviation challenges, and the capacity for system expansion promises real potential for Howell customers in the aviation community.

Milton continues, “This strategic alliance with Blackhawk Modifications combines our engine expertise with an MRO industry leader. We are approaching the project as a gateway to a modular system that will offer innovative solutions for the aviation community as a whole.”
