[Docket No. 95-ANE-13; Amendment 39-9453; AD 95-25-08]
Airworthiness Directives; Royal Inventum Company DR1 and DR6
Series Galley Water Heaters
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to Royal Inventum Company DR1 and DR6 Series Galley Water
Heaters, that requires the installation of a pressure relief valve, and
3-phase safety devices on each Royal Inventum Company DR1 and DR6
series galley water heater. This amendment is prompted by a report of a
Royal Inventum DR6 water heater explosion during an overheat test at a
maintenance facility. The actions specified by this AD are intended to
prevent explosions of Royal Inventum Company DR1 and DR6 series galley
water heaters, which could cause personal injury or galley damage to
the aircraft.
DATES: Effective May 20, 1996.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of May 20, 1996.
ADDRESSES: The service information referenced in this AD may be
obtained from B/E Aerospace, Inventum Galley Products Division (Royal
Inventum Company), P.O. Box 1152, 3430 BD Nieuwegin, The Netherlands.
This information may be examined at the Federal Aviation Administration
(FAA), New England Region, Office of the Assistant Chief Counsel, 12
New England Executive Park, Burlington, MA; or at the Office of the
Federal Register, 800 North Capitol Street NW., suite 700, Washington,
DC.

(617) 238-7155, fax (617) 238-7199.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to Royal Inventum Company DR1 and DR6
series galley water heaters was published in the Federal Register on
June 21, 1995 (60 FR 32287). That action proposed to require the
installation of new pressure relief valves, and 3-phase safety devices
on each Royal Inventum Company DR1 and DR6 series galley water heater.
The actions would be required to be in accordance with Inventum
Bilthoven-Holland Service Bulletin's (SB's) 25__330, Revision 1, dated
September 28, 1977; SB 25__331, Revision 1, dated September 28, 1977;
and Inventum Alert Service Bulletin (ASB) DR1/DR6-25-4, Revision A,
dated December 6, 1993, that specify the installation of a pressure
relief valve; and Inventum Bilthoven-Holland SB's 25__340, dated July
7, 1977; SB 25__344, dated January 18, 1978; SB 25__345, dated February
16, 1978; SB 25__346, dated February 16, 1978; and Inventum ASB DR1/
DR6-25-5, Revision A, dated December 6, 1993, that specify the
installation of 3-phase safety devices. The Director-General of Civil
Aviation of the Netherlands has classified these service bulletins as
mandatory and issued Airworthiness Directive BLA 93-168 (AB), dated
December 17, 1993, in order to assure the airworthiness of these water
heaters.
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comments received.
One commenter states that the Inventum DR6 series water heaters
have been used on Boeing 747, 757 and 767 series aircraft and
recommends that the Applicability be changed to show these aircraft.
The commenter further states that they were unable to determine usage
of Inventum DR1 and DR6 series water heaters on Boeing 727 and 737
series aircraft. The FAA agrees. Since the Boeing 727 and 737 series
aircraft usage was given to the FAA by the Director-General of Civil
Aviation of the Netherlands, the FAA will retain reference to the
Boeing 727 and 737 series aircraft in the Applicability section.
Reference to the Boeing 747, 757 and 767 series aircraft will be added.
Operators are cautioned, however, not to read the list of aircraft as
an exclusive list of the aircraft that may have the affected water
heaters installed. This AD applies to all aircraft with an affected
water heater, whether or not listed.
One commenter supports the AD.
After careful review of the available data, including the comments
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule with the changes described
previously. The FAA has determined that these changes will neither
increase the economic burden
[[Page 11528]]
on any operator nor increase the scope of the AD.
The FAA estimates that 250 water heaters installed on aircraft of
U.S. registry will be affected by this AD, that it will take
approximately six and one half work hours per water heater to
accomplish the required actions, and that the average labor rate is $60
per work hour. Required parts will cost approximately $250 per
aircraft. Based on these figures, the total cost impact of the AD on
U.S. operators is estimated to be $94,500.
The regulations adopted herein will not have substantial direct
effects on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government. Therefore, in
accordance with Executive Order 12612, it is determined that this final
rule does not have sufficient federalism implications to warrant the
preparation of a Federalism Assessment.
For the reasons discussed above, I certify that this action (1) is
not a ``significant regulatory action'' under Executive Order 12866;
(2) is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and (3) will not have a
significant economic impact, positive or negative, on a substantial
number of small entities under the criteria of the Regulatory
Flexibility Act. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 USC 106(g), 40101, 40113, 44701.
39.13 [Amended]
2. Section 39.13 is amended by adding the following new
airworthiness directive:
95-25-08 Royal Inventum Company: Amendment 39-9453. Docket 95-ANE-
13.
Applicability: Royal Inventum Company DR1 and DR6 series galley
water heaters, installed on but not limited to Boeing 727, 737, 747,
757 and 767 series, McDonnell Douglas DC-9 series; and Fokker F.28
series (except Mk. 0100) aircraft.
Note: This AD applies to each water heater identified in the
preceding applicability provision, regardless of whether it has been
modified, altered, or repaired in the area subject to the
requirements of this AD. For water heaters that have been modified,
altered, or repaired so that the performance of the requirements of
this AD is affected, the owner/operator must use the authority
provided in paragraph (b) to request approval from the FAA. This
approval may address either no action, if the current configuration
eliminates the unsafe condition, or different actions necessary to
address the unsafe condition described in this AD. Such a request
should include an assessment of the effect of the changed
configuration on the unsafe condition addressed by this AD. In no
case does the presence of any modification, alteration, or repair
remove any water heater from the applicability of this AD.
Compliance: Required as indicated, unless accomplished
previously.
To prevent possible explosion of water heaters that could cause
personal injury and aircraft damage, accomplish the following:
(a) Within 90 days after the effective date of this AD install a
pressure relief valve in accordance with Inventum Alert Service
Bulletin (ASB) DR1/DR6-25-4, Revision A, dated December 6, 1993, or
Inventum Service Bulletin (SB) 25__330, Revision 1, dated September
28, 1977; or SB 25__331, Revision 1, dated September 28, 1977; and
two 3-phase safety devices in accordance with Inventum ASB DR1/DR6-
25-5, Revision A, dated December 6, 1993, or SB 25__340, dated July
7, 1977; SB 25__344, dated January 18, 1978; or SB 25__345, dated
February 16, 1978; or SB 25__346, dated February 16, 1978.
(b) An alternative method of compliance or adjustment of the
compliance time that provides an acceptable level of safety may be
used if approved by the Manager, Boston Aircraft Certification
Office. The request should be forwarded through an appropriate FAA
Principal Maintenance Inspector, who may add comments and then send
it to the Manager, Boston Aircraft Certification Office.
Note: Information concerning the existence of approved
alternative methods of compliance with this airworthiness directive,
if any, may be obtained from the Boston Aircraft Certification
Office.
(c) Special flight permits may be issued in accordance with
sections 21.197 and 21.199 of the Federal Aviation Regulations (14
CFR 21.197 and 21.199) to operate the aircraft to a location where
the requirements of this AD can be accomplished.
(d) The modification and inspection shall be done in accordance
with the following service bulletins:
