On December 29, 2010 the NTSB released its much anticipated safety recommendations to the FAA.
Three of the recommendations are that hover performance charts published by helicopter manufacturers reflect true performance of helicopters in all conditions for which charts are applicable. The FAA should develop and implement surveillance program for 14 CFR Part 135 (Title 14 of the Code of Federal Regulations concerned with operating requirements for commuter and on demand operations and rules governing persons on board such aircraft) with aircraft that can operate as both public and civil aircraft. Also, the FAA should require installation of fuel tanks that meet requirements of 14 CFR 29.925 (fuel system crash resistance) on S-61 helicopters for passenger transport.
The NTSB issues safety recommendations to federal, state, and local government agencies and to other industry and organizations in a position to improve transportation safety. These recommendations are based on thorough, accurate, and independent investigations and studies and although the NTSB has no formal authority to regulate the transportation industry, it provides timely, well-considered recommendations to improve transportation safety.
The large number of emergency medical helicopters crashes in recent years – at least 35 lives lost since 2007 – prompted investigations by the NTSB which resulted in this week’s recommendations to the FAA.
We have taken note of these recommendations and will provide our insight on them in the coming weeks.
For a complete list of the recommendations, please continue reading.
1. Require that the hover performance charts published by helicopter manufacturers reflect the true performance of the helicopter in all conditions for which the charts are applicable, including light and variable wind conditions. (A-10-148)
2. Develop and implement a surveillance program specifically for 14 Code of Federal Regulations (CFR) Part 135 operators with aircraft that can operate both as public aircraft and as civil aircraft to maintain continual oversight ensuring compliance with 14 CFR Part 135 requirements. (A-10-149)
3. Take appropriate actions to clarify Federal Aviation Administration (FAA) authority over public aircraft, as well as identify and document where such oversight responsibilities reside in the absence of FAA authority. (A-10-150)
4. Require the installation of fuel tanks that meet the requirements of 14 Code of Federal Regulations 29.952 on S-61 helicopters that are used for passenger transport. (A-10-151) Require that S-61 helicopters that are used for passenger transport be equipped with passenger seats and seat mounting structures that provide substantial improvement over the requirements of Civil Air Regulations 7.260, such as complying with portions of 14 Code of Federal Regulations 29.561 and 29.562. (A-10-152)
5. Require operators of transport-category helicopters to equip all passenger seats with restraints that have an appropriate release mechanism that can be released with minimal difficulty under emergency conditions. (A-10-153)
6. Require that Advisory Circular 21-34 be used to evaluate all shoulder harness retrofit installations and to determine that the installations reduce the risk of occupant injury. (A-10-154)
7. Require operators of Sikorsky S-61 helicopters with General Electric model CT58-140 engines to install 10-micron airframe fuel filters. (A-10-155)
8. Require Carson Helicopters, Inc., to put a conspicuous notification on the title page of the Instructions for Continuing Airworthiness that accompany its supplemental type certificate for installing side-mounted seats indicating that the installation does not provide enhanced occupant protection over that provided by the originally installed seats and meets Civil Air Regulations 7.260 standards. (A-10-156)
9. Require all applicants for supplemental type certificate (STC) seat installations in any type of aircraft to put a conspicuous notification on the title page of the Instructions for Continuing Airworthiness that accompany the STC indicating whether the installation provides enhanced occupant protection over that provided by the originally installed seats and the certification standard level met by the seating system. (A-10-157)
10. Require supplemental type certificate (STC) applicants to improve the crashworthiness design of the seating system, such as complying with portions of 14 Code of Federal Regulations 29.561 and 29.562, when granting STC approval for older transport-category rotorcraft certificated to Civil Air Regulations 7.260 standards. (A-10-158)
Also, the National Transportation Safety Board reiterates the following previously issued recommendation to the Federal Aviation Administration:
Do not permit exemptions or exceptions to the flight recorder regulations that allow transport-category rotorcraft to operate without flight recorders, and withdraw the current exemptions and exceptions that allow transport- category rotorcraft to operate without flight recorders. (A-06-18)

All sound recommendations. What would prevent operators from adopting and adapting these safety recommendations in advance of the FAA mandate or mitigation on these items? Isn’t the liability aspect of having knowledge of these issues motivation enough to take a pro-active approach to flights with passengers? Do we rely to heavily on the minimum requirements established by the FAR’s? So many questions….
