In the EC 155 B1 flight manual APPROVED ALT. / TEMP. ENVELOPE IS FROM - 40 TO +50 .

But in the helicopters TYPE CERTIFICATE DATA SHEET due to some modification the operating temp. is different .

My question is , 

Which one should be considered for the flight , FLIGHT MANUAL or  Helicopter's TYPE CERTIFICATE DATA SHEET ?

Many tnx

The rotorcraft flight manual is your regulatory source for operating information.

 

§14 CFR 91.9   Civil aircraft flight manual, marking, and placard requirements.

 

 Except as provided in paragraph ( d ) of this section, no person may operate a civil aircraft without complying with the operating limitations specified in the approved Airplane or Rotorcraft Flight Manual, markings, and placards, or as otherwise prescribed by the certificating authority of the country of registry.

 

§14 CFR 29.1581   General.

 

( a ) Furnishing information. A Rotorcraft Flight Manual must be furnished with each rotorcraft, and it must contain the following: 

 

(1) Information required by §§29.1583 through 29.1589.

 

§29.1583   Operating limitations.

§29.1585   Operating procedures.

§29.1587   Performance information.

§29.1589   Loading information.

 

By the way, on which page of the TCDS did you note the conflicting information?

 

TYPE CERTIFICATE DATA SHEET No. H10EU

 

Model EC 155B and Model EC155B1
FAR 21.29 and FAR 29 Amendment 29-1 through Amendment 29-40..

 

Conflicts with Other FAA Orders. The guidance in this order may conflict with that in other FAA orders and directives. This situation may arise inadvertently or because it is impractical to revise all orders simultaneously. In such a case, use the order with the most recent date.

 

 If the guidance in this order conflicts with 14 CFR, 14 CFR takes precedence. Inspectors should refer questions about such conflicts to their immediate supervisors. Supervisors and managers may contact the respective AFS division through the Regional Office (RO) to resolve such questions. - FAA 8900.1
