B. Reason 

(1) 

(2) 

(3) 

(4) 

(5) 

Problem 

Cracking of the front combustion liner diffuser case bleed struts and 

front section inner and outer liners may occur after extended use. 

Additionally, Phase 2 combustion liners have exhibited burning/holing of 

the heatshield inner ramp corners which may cause premature removal. 

Evidence 

There have been a few reported incidents of combustor head rejection due 

to cracking with the Phase 2 combustion liner. In addition there have 

been several incidents with the Improved Package 1 combustion liner 

which has the same basic head assembly. The cracking can result in loss 

of material which in a small number of cases has led to downstream 

secondary distress. 

Substantiation 

The changes introduced by this Service Bulletin have completed over 

1,000 cycles of development engine testing at temperature conditions 

representative of those likely to be encountered by engines in service 

after which the combustor was found to be in good condition. 

Engineering analysis confirms a reduction in stresses in the affected 

area when a strengthened head is fitted and the problem is alleviated. 

Objective 

Incorporation of the changes introduced by this Service Bulletin 

(Modification) is designed to maintain reliability. It is anticipated 

that a significant increase in combustor head and heatshield life will 

result upon incorporation of this Service Bulletin (Modification).

C. Description 

(1) The changes introduced by this Service Bulletin are as follows: 

5 

G 

C 

.- 

-Ls 

E 

‘C 

n 

A revised front combustion liner assembly is introduced similar to the 

existing item except for the following: 

(a> 

(b) 

cc> 

Cd) 

(e> 

The combustion liner head with diffuser, diffuser walls and bleed 

offtake struts is produced in C263 material instead of N75 material. 

Reduced axial length bleed offtake struts with increased leading edge 

radius. 

A revised heatshield design featuring a modified cooling hole pattern 

and aluminised surface finish. 

The meter panel cooling hole pattern is revised to match the revised 

heatshield and ensure sufficient cooling air flow. 

The revised meter panel features an increased cooling flow burner 

seal ring. 

(2) Existing front combustion liner assemblies can be reworked, see Fig 1 to 

5. 

(3) A combustion liner, head section assembly is required to accomplish 

rework of the front combustion liner. 

(4) For relationship with other Service Bulletins (Modification) see 1.J. 

D. Compliance 

R RB211-524H-36 series engines and modules 

R MANDATORY 

R This Service Bulletin (Modification) is classified MANDATORY by the United 

R Kingdom Civil Aviation Authority (C.A.A.) and must be accomplished by 10th 

R December, 1997.

RECOMMENDED (3) 

Rolls-Royce recommends that this Service Bulletin (Modification) be 

accomplished, commensurate with Operators experience, when the part 

involved requires renewal because of its condition.
