NTSB CITES POOR DECISIONMAKING AND SPATIAL DISORIENTATION AS 
CAUSE OF HAWAIIAN AIR TOUR ACCIDENT

************************************************************

Washington, D.C. - In a report adopted today, the National 
Transportation Safety Board determined that the probable 
cause of a fatal crash of an air tour helicopter in Hawaii 
was "the pilot's decision to continue flight into an area of 
turbulent, reduced visibility weather conditions, which 
resulted in the pilot's spatial disorientation and loss of 
control of the helicopter."  

        The accident occurred on September 24, 2004, when the 
Bell 206B helicopter, operated by Bali Hai Helicopter Tours, 
Inc., conducting an air tour flight on the island of Kauai, 
encountered adverse weather conditions and crashed into 
mountainous terrain.  The pilot and all four passengers were 
killed in the crash.

        "The air tour industry in Hawaii serves hundreds of 
thousands of paying passengers each year and the public 
deserves an appropriate level of safety when they embark on 
an air tour," said NTSB Chairman Mark V. Rosenker.  " It is 
my fervent hope that the FAA will move quickly on our 
recommendations."

        The Board's report examined local weather training for 
newly hired Hawaii air tour pilots, air tour operational 
practices, Federal Aviation Administration (FAA) 
surveillance of air tour operators, and flight tracking and 
on-board weather technology for Hawaii air tour aircraft.

        Experienced local pilots interviewed for the 
investigation noted that helicopter operations on Kauai can 
be challenging due to the terrain, mountain winds, and 
rapidly changing cloud conditions.  A review of the eight 
weather-related accidents that have occurred in Hawaii since 
1994 found that four involved pilots who were relatively new 
to air tour operations in Hawaii, three of whom, including 
the accident pilot, had been operating for less than two 
months.  The Board cited the pilot's inexperience in 
assessing local weather conditions as a contributing factor 
and recommended that the FAA develop and require a cue-based 
training program for pilots that specifically addresses 
local weather phenomena and in-flight decision-making.

        Bali Hai's helicopter tours departed from Port Allen 
Airport (PAK), a general aviation airport with no buildings 
or shelters, and Bali Hai did not provide any airport 
shelter or restroom facilities for their employees or 
customers.  Further, a review of scheduling practices 
discovered that pilots typically flew between seven or eight 
hours a day without lunch or bathroom breaks.  Between 
tours, pilots would remain in the helicopter with rotors 
turning, to reduce wear on the engine. The Board concluded 
that these operational practices, although permitted under 
Federal regulations, likely had an adverse impact on pilot 
decision-making and performance.  Bali Hai's operational 
practices were cited as a contributing cause and the Board 
recommended that the FAA establish best scheduling practices 
to ensure acceptable pilot performance and safety and 
require commercial air tour operators to adhere to these 
practices.

        In addition to challenging scheduling practices, the 
review of Bali Hai's operations found significant 
discrepancies with aircraft maintenance procedures and 
logbooks.  Although under the jurisdiction of the Honolulu 
Flight Standards District Office (FSDO), because Bali Hai 
operated under the less stringent 14 CFR Part 91 operating 
rules, there are no requirements for FAA inspection of 
operations. In fact, prior to this accident, Bali Hai had 
never received an FAA operations inspection.  The Board 
concluded that the public would benefit from air tour 
regulations that provide increased oversight and additional 
safety requirements for Part 91 air tour operators.  The 
lack of FAA surveillance was cited as a contributing cause 
and the Board recommended that the FAA develop and enforce 
safety standards for all commercial air tour operators that 
include at a minimum, pilot training programs, special 
airspace restrictions, maintenance policies, and flight 
scheduling procedures.  The Board also noted that these 
recommended safety standards are not required by the FAA's 
recently released 14 CFR Part 136 air tour rules.

        Finally the NTSB noted that Hawaii's mountainous 
landscape, limited air traffic control coverage, challenging 
weather, and high-density air traffic make it a prime 
candidate for the National Automatic Dependent Surveillance-
Broadcast (ADS-B) program and recommended that the FAA 
accelerate the implementation of ADS-B infrastructure 
capable of providing services to the aircraft flying air 
tour routes in Hawaii.  The Board further recommended that 
the FAA require Hawaii air tour operators to equip their 
aircraft with ADS-B technology within one year of the 
installation of a functional national ADS-B program.

        A synopsis of the Board's report, including the 
probable cause and safety recommendations, is available on 
the Board's website, www.ntsb.gov.  The Board's full report 
will be available on the website in several weeks.
