to be sampled ten contiguous originally

planted tree sites will be sampled

within the rows. Only trees more than

five years old will be harvested for the

sample. For example, if it is determined

that five rows are to be sampled and 10

trees in the five rows are to be sampled,

then a total of 50 trees are to be sampled

((10 original tree sites) × (5 rows)= 50

trees). A total of 4600 pounds will be

harvested from the sample trees which

is divided by 50 trees to obtain a yield

of 92 pounds per tree. To find the yield

for the block, 92 pounds is multiplied

by 880 trees that were mapped in the

block to yield 80,960 pounds per block.

The harvested tonnage will be converted

to a volume that represents the entire

block of cherries. The grower should

inform the Board when the samples are

being taken so a compliance officer can

observe the sampling. The compliance

officer would be allowed to confirm that

the block has been diverted.

(3) Partial block diversion. Partial

block diversion will also be

accomplished using maps supplied by

the grower. Sampling will be done as in

whole block diversion except that only

partial blocks would be selected and

sampled. Growers may divert one

partial block per year. Such block must

be mapped and would be sampled as

described under whole block diversion.

Rows used in partial block diversion

must be contiguous.

(4) In-orchard tank diversion. Growers

wishing to in-orchard tank divert must

pick the cherries to be diverted and

place them in harvesting tanks. A

compliance officer would then probe

the tanks for volume measurement and

observe the destruction of the cherries

on the grower’s premises. Growers

wishing to take advantage of this option

must have at least 10 tanks ready for

diversion. The compliance officer has

up to five days to come to the grower’s

premises to observe the diversion after

being contacted.

(c) Compliance. Growers who

voluntarily participate in the grower

diversion program must sign and file

with the Board a Grower Diversion

Application. By signing the application,

a grower agrees to the terms and

conditions of the grower diversion

program as contained in these

regulations. To be eligible to receive

diversion credit, growers voluntarily

choosing to divert cherries must meet

the following terms and conditions:

(1) In order to receive a certificate, a

grower must demonstrate, to the

satisfaction of the Board, that rows or

trees which were selected for diversion

were not harvested. Trees four years old

or younger do not qualify for diversion.

(2) The grower must furnish the Board

with a total harvested production

amount so the Board can calculate the

amount of grower diversion tonnage to

be placed on the diversion certificate.

The Board will confirm the grower’s

production amount with information

provided by handlers (to which the

grower delivers cherries) on Board form

Number Two.

(3) The grower must agree to allow a

Board compliance officer to visit the

grower’s orchard to confirm that

diversion has actually taken place. If the

terms and conditions for whole block,

partial block or in-orchard tank

diversion are not completed, the Board

shall not issue the grower a diversion

certificate. If a grower who chooses

random row diversion harvests rows

that were designated not to be

harvested, the grower should inform the

Board immediately of the error. The

grower will then be required to divert

twice the amount (rows or trees)

incorrectly harvested to correct the

mistake. The grower will still receive a

diversion certificate equal to the original

requested amount. However, in

instances where a grower is at the end

of harvesting the orchard and fails to

divert a complete block or specified

rows, the Board shall multiply by two

the difference between the original

diversion amount and the actual

diverted amount. The Board shall

subtract that amount from the diversion

application amount. Thus, the grower

would receive a grower diversion

certificate equal to a portion of the

originally requested amount. If the

grower does not inform the Board of

such errors, the grower will not receive

a diversion certificate.

Conditions No. 33–001–SC]

Special Conditions: Turbomeca S.A.,

Model Arriel 2S1 Turboshaft Engine

AGENCY: Federal Aviation

Administration (FAA), DOT.

ACTION: Final special conditions.

SUMMARY: These special conditions are

issued for the Turbomeca S.A., of

Bordes, France, Model Arriel 2S1

turboshaft engine. This engine was

validated on June 10, 1996, by the

Federal Aviation Administration (FAA)

and Type Certificate No. E00054EN was

issued. The engine will have an

additional new novel or unusual engine

rating. The applicable airworthiness

regulations do not contain adequate or

appropriate safety standards for this

design feature. These special conditions

contain the additional safety standards

the Administrator considers necessary

to establish a level of safety equivalent

to that established by existing

airworthiness standards.

EFFECTIVE DATE: June 19, 1998.

SUPPLEMENTARY INFORMATION:

Background

On March 19, 1998, Turbomeca S.A.,

applied for an amendment to Type

Certificate No. E00054EN to include a

new 30-minute engine rating to Model

Arriel 2S1 turboshaft engine. The rating

is intended for use up to 30 minutes at

any time after takeoff in a flight for

performing search and rescue missions.

The Model Arriel 2S1 turboshaft engine

will be rated at 30-Second one engine

inoperative (OEI), 2-Minute OEI,

Continuous OEI, 30-Minute, Takeoff,

and Maximum Continuous ratings.

The applicable airworthiness

requirements do not contain a definition

for a ‘‘30-minute’’ power rating, and do

not contain adequate or appropriate

safety standards of this new and

unusual engine rating. The FAA

published a notice of proposed special

conditions on April 29, 1998 (63 FR

23402), Docket No. 98–ANE–119, and

requested public comments.

Type Certification Basis

Under the provisions of Title 14 of the

Code of Federal Regulations (14 CFR)

§ 21.101 Turbomeca S.A., must show

that the Model Arriel 2S1 turboshaft

engine meets the requirements of the

applicable regulations in effect on the

date of the application, or the applicable

provisions of the regulations

incorporated by reference in Type

Certificate No. E00054EN. The

regulations incorporated by reference in

the type certificate are commonly

referred to as the ‘‘original type

certification basis’’. The regulations
33530 Federal Register / Vol. 63, No. 118 / Friday, June 19, 1998 /Rules and Regulations

incorporated by reference in Type

Certificate No. E00054EN are 21.29 and

part 33, effective February 1, 1965, as

amended by Amendments 33–1 through

33–14, and Special Conditions SC–33–

ANE–05, Docket No. 95–ANE–46,

published on April 15, 1996 (61 FR

16375).

The Administrator finds that the

applicable airworthiness regulations in

part 33, as amended, do not contain

adequate or appropriate safety standards

for the additional new engine rating for

the Model Arriel 2S1 turboshaft engine

because it is a novel or unusual engine

rating feature, special conditions are

prescribed under the provision of 14

CFR 21.16.

Special conditions, as appropriate, are

issued in accordance with 14 CFR 11.49

after public notice, as required by

§§ 11.28 and 11.29(b), and become part

of the type certification basis in

accordance with 14 CFR 21.101(b)(2).

Novel or Unusual Design Features

The Turbomeca S.A., Model Arriel

2S1 turboshaft engine will incorporate

the following novel or unusual design

features: Rated 30-minute power. The

power available for rotorcraft hovering

to perform maritime search and rescue

missions is currently limited to the

maximum continuous rating power

under current part 33. The proposed

‘‘30-minute power’’ rating would

provide higher power level than

currently available for use up to 30

minutes at any time between takeoff and

landing in one flight. This new rating

will enhance rotorcraft safety through

the availability of increased power for

hovering operations calling for greater

than maximum continuous power.

Discussion of Comments

Interested persons have been afforded

the opportunity to participate in the

making of these special conditions. No

comments were received on the special

conditions as proposed. After careful

review of the available data, the FAA

has determined that air safety and the

public interest require the adoption of

the special conditions without change.

Applicability

As discussed above, these special

conditions are applicable to the

Turbomeca S.A., Model Arriel 2S1

turboshaft engine. Should Turbomeca

S.A., of Bordes, France, apply at a later

date for a change to the type certificate

to include another model incorporating

the same or novel or unusual design

feature, the special conditions would

apply to that model as well under the

provisions of 14 CFR 21.101(a)(1).

These special conditions provide

necessary increased hover time to

enable operators to better perform

critical, life-saving search and rescue

missions, particularly in overwater

situations. For this reason and because

a delay would not be in the public

interest, the FAA has determined that

good cause exists for adopting these

special conditions immediately upon

publication.

Conclusion

This action affects only certain novel

or unusual design features on one model

of engines. It is not a rule of general

applicability and it affects only the

applicant who applied to the FAA for

approval of these features on the engine.

ACTION: Final rule.

SUMMARY: This amendment adopts a

new airworthiness directive (AD),

applicable to CFM International (CFMI)

CFM56–2, –2A, –2B, –3, –3B, and –3C

series turbofan engines, that requires a

one-time eddy current inspection (ECI)

for cracks or gouges in certain high

pressure turbine rotor (HPTR) disks.

This amendment is prompted by a

report of a HPTR disk found to have a

crack in a rim bolt hole during a routine

shop manual ECI. The actions specified

by this AD are intended to prevent the

potential for an uncontained failure of

the HPTR disk, which could result in an

inflight engine shutdown, aborted

takeoff, or damage to the aircraft.

DATES: Effective July 20, 1998.

The incorporation by reference of

certain publications listed in the

regulations is approved by the Director

of the Federal Register as of July 20,
