**AFFECTED AIRCRAFT**

Bell Model 206B helicopters: registration no. N16849, serial no. 2355;
and registration no. N49588, serial no. 1726.

**PURPOSE**

The purpose of this notification is to advise all aircraft owners,
operators, maintenance organizations, manufacturers, and parts
distributors regarding improper maintenance and operations performed on
Bell Model 206B helicopters with registration no. N16849, serial no.
2355, and registration no. 49588, serial no. 1726. Both aircraft were
owned and operated by Bali Hai Helicopter Tours, Inc.

**BACKGROUND**

Information received during a Federal Aviation Administration (FAA)
investigation of the fatal accident involving aircraft N16849 revealed
that Bali Hai Helicopter Tours, Inc. (Bali Hai), located at P. O. Box
626, Hanapepe, HI 96716, did not use or have in place an accurate method
for tracking accumulated time on the two helicopters and their
components. No times had been recorded for maintenance, repositioning,
FAA check-ride, or all other flights not associated with flightseeing
tours. When tracking flightseeing tours, Bali Hai recorded the projected
time of the tours and not the actual flight time.

Evidence indicated that the hour meter for both helicopters had been
inoperative and disabled for several years. In addition, pilots did not
maintain any flight log that included entries for flight time. The
information available is insufficient to determine the total time
accumulated on the aircraft and their components. Therefore, the current
status of the life-limited and overhauled parts of each airframe,
engine, rotor, and appliance cannot be established.

In addition, evidence indicated noncompliance with information issued in
Airworthiness Directives and technical and service bulletins as well as
an absence of tracking scheduled inspections.

The table below presents a *partial list* of components that were
installed on the aircraft.

**RECOMMENDATIONS**

Regulations require that type-certificated products conform to their
type design. Aircraft owners, operators, manufacturers, maintenance
organizations, and parts suppliers and distributors should inspect their
aircraft, maintenance records, and/or parts inventories for any of the
referenced parts. If any of these parts have been installed on aircraft,
appropriate action should be taken. If any are found in existing
aircraft stock, the parts should be quarantined to prevent installation
until a determination can be made regarding their eligibility for
installation.

**FURTHER INFORMATION**

Further information concerning this investigation, and guidance
regarding the above-referenced parts, can be obtained from the FAA
Flight Standards District Office (FSDO) given below. The FAA would
appreciate any information concerning the discovery of the
above-referenced parts from any source, the means used to identify the
source, and the actions taken to remove the parts from aircraft and/or
stock.
