1. PLANNING INFORMATION 
 
A. Effectivity 
 
This Vendor Service Bulletin details the procedure to replace the Pressure Relief 
Valve (PRV), Part Number 42F0026 by :  
 
- 42F0029 : New PRV P/N for the PRV affected batch (remove PRV P/N 
42F0026).  
- 42F0030 : New PRV P/N for the PRV not affected batch (rename PRV P/N 
42F0026).  
 
The impacted Pressure Relief Valve are installed into the following Hydraulic Tank 
(see Table 1).

C. Reason 
 
(1) Issue: Several instances of in -service PRV air leakage have been reported. In 
certain operating conditions of the hydraulic tank circuit, the seal pops o ut of its 
groove and stuck the valve open. This is confirmed during the disassembly of 
the valves. These symptoms were found into Pressure Relief Valve Part Number 
42F0026.  
During the analysis some PRV modification that could improve robustness have 
been pointed : 
- Change of Poppet seal material to reduce swelling  
- Restrain the dimensions of the seal grove to increase holding 
 
(2) Action: Replace the impacted Pressure Relief Valve Part Number 42F0026. 
Refer to ATT01 for Part Number Applicability.  
For the non-impacted Pressure Relief Valve, rename them with a label. Refer to 
ATT03 for the procedure to perform. 
 
(3) Benefit: The Service Bulletin 42-29-006 describes the reasons and the way to 
rename the non-impacted PRV PN 42F0026. 
The procedure for the replacement of the impacted Pressure Relief Valve Part 
Number 42F0026.  
 
D. Description 
 
This Service Bulletin provides authorization and instruction to change the Pressure 
Relief Valve Part Number 42F0026.  
You find the list of PRV to change in annexe : ATT01.  
 
All the affected PRV are replaced by the PRV new design : 42F0029.  
The others PRVs are identified by a new label : 42F0030   
In all cases, the hydraulic tank must be identified with a new Part Number (see Table 
1 and procedure ATT02).  
 
E. Compliance 
 
 Incorporation of this service bulletin is mandatory and should be accomplished at the 
earliest opportunity. 
 
F. Approval 
 
The technical content of this document is approved under the authority of DOA  ref. 
 EASA.21J.031

VAPORS AND MISTS, WHENEVER SKYDROL VAPOR IS PRESENT. IF 
ANY EYE CONTACT OR  SKIN CONTACT OCCURS, RINSE OUT WITH 
WATER. 
 
Before starting, the PN of the PRV must be checked to know if the PRV is suspect or not 
(see ATT01). If the S/N of the PRV is not visible, the PRV must be removed 
 
1) A) Replacing a PRV suspect :
