FAA Approves Amendment for UAM & Lower Fuselage Radome STC

Amended UAM STC Adds Greater Flexibility & Serviceability

On January 30, 2017, Pro Star Aviation LLC obtained Federal Aviation Administration (FAA) approval for an amendment to Supplemental Type Certificate (STC) SA00334BO – Installation of Universal Antenna Mount (UAM) & Lower Fuselage Radome, an STC applicable to Textron Aviation (Beechcraft, Hawker Beechcraft, Raytheon) B300 (Super King Air 350) and B300C (Super King Air 350C) airframes. The amendment, a result of feedback from industry users, makes the design of the STC more versatile and mission flexible, while improving overall system inspection methods and operations.

Amendment Details:

  • Operational configurations were expanded to allow up to four antennas to be installed on the UAM when no radome is installed.
  • An optional design for aircraft pressure feedthru panels was added, allowing the panels to be removed from the interior of the aircraft when the radome and UAM are installed. This optional design facilitates the required visual inspections of the UAM and radome, allowing them to be accomplished without having to remove the radome and/or its sensitive payload.
  • UAM visual inspection intervals were increased to be accomplished at 800 hrs/Phase 4 inspection in the applicable Instructions for Continued Airworthiness (ICA), aligning them with similar inspections.
  • Deviations found in follow-on installations in radome mounting points due to variations in aircraft production were incorporated.

Pro Star Aviation, with the support of its in-house Organizational Designation Authorization (ODA) delegation, routinely performs engineering and design work for specialized mission equipment, such as the UAM & Lower Fuselage Radome mentioned above, and deeply appreciates the feedback from users within the industry.

FAA Approves STC - ADS-B Out Solution for MST-67A Equipped Aircraft

Pro Star Aviation, with support from its in-house Organization Designation Authorization (ODA) delegation, obtained Federal Aviation Administration (FAA) Supplemental Type Certificate (STC) ST00373BO on January 5, 2017, for the Installation of Rockwell Collins TDR-94D Transponders with ADS-B Out.

In partnership with Rockwell Collins, Pro Star Aviation designed an STC to address ADS-B Out compliance for the vast number of aircraft equipped with BendixKing MST-67A transponders associated with the BendixKing CAS-67A or B TCAS II system.

Currently, BendixKing does not offer an upgrade program for MST-67A units to comply with ADS-B Out. Since the MST-67A transponders are a vital component of the CAS-67A or B TCAS II system, it is important to retain the integrity and approval of the existing TCAS installation while making the aircraft compliant with the 2020 ADS-B Out mandate.

Since the Rockwell Collins TDR-94D transponder is the only non-integrated transponder approved in the BendixKing installation manual that is compatible with the CAS-67A or B, Pro Star determined it to be the best replacement for the non-compliant MST-67A transponder.

The design of the STC, utilizes a pair of Rockwell Collins TDR-94D units that fit in the same location as the MST-67A units. The existing wiring, antennas and the controller can be retained. In its new configuration, the TCAS system is both manufacturer tested and STC approved to be fully compliant using the new transponders.

The STC features an Approved Make and Model List covering, but not limited to, the following MST-67A equipped aircraft; Hawkers, Challenger, Falcons, Gulfstreams, Westwards, Saberliners and Citations.

While there are other solutions to replace the outdated MST-67A units, only the Rockwell Collins TDR-94D solution has been a BendixKing approved option for the CAS-67A or B TCAS II system since the system was first offered nearly two decades ago.

According to Pro Star Aviation’s Director of Business Development, Jeffrey Shaw,

“This STC is particularly useful in situations where there is concern for the integrity of the existing TCAS II system when changing transponder manufacturers in order to comply with ADS-B Out.”

The FAA has indicated that upgrading transponders to comply with ADS-B will not compromise the integrity of the existing TCAS, however changing transponder manufacturer all together is not specifically covered by the spirit of the FAA’s statement. Jeffrey went on to say,

“We are very pleased to be able to use a transponder type covered in the original BendixKing installation manual. The TDR-94D is the only model that meets the ADS-B mandate and is covered by the CAS 67 installation manual.”
