(M) (O) May be inoperative provided:

 

 

 

 

 

(a)         Lavatory waste receptacle is empty,

(b)         Associated lavatory door is locked closed and placarded to prohibit passengers from entering,

(c)         Affected lavatory is used only by crew members, and

(d)         Associated lavatory is not used for storage of any inflammable or combustible materials.

 

 

 

 

 

Procedures

(M) to provide instructions to lock closed and placard the inoperative lavatory.

(O) to provide procedures to brief crew members.

0

(M) (O) May be inoperative provided:

 

 

 

 

 

(a)         Lavatory waste receptacle fire-extinguishing system is verified operative, and

(b)         Procedures are established and used to check periodically absence of smoke in affected lavatory, and

 

 

 

 

 

Procedures

(M) To provide instructions to verify/test the agent bottle of the lavatory waste receptacle fire-extinguishing system.

(O) To provide procedures to ensure affected lavatory is visited periodically by the cabin crew and not used for stowage of any inflammable or combustible materials.

26-17-1C

(Aeroplanes with passenger capacity of less than 20)

C

-

0

May be inoperative.

 

Additional considerations:

Use of the affected lavatory by the crew members does not authorise storage of inflammable or combustible materials, such as in-flight service waste bags.

The definition of the interval for the periodic check by the crew may appear as arbitrary and this guidance does not mandate any specific interval.

It is proposed to let the operator develop its own procedure depending on the conducted operations under the control of the authority approving the MEL.

Regarding the extinguisher verification, bearing in mind the system is usually verified only through maintenance programme with a period of time between two consecutive checks exceeding the proposed rectification interval, a one-time check before the release for a B (3 days maximum) interval is judged acceptable.

Relief provided under 26-17-1C is applicable only if the installation of lavatory smoke detection system is not required by the type certification basis.

(M) (O) Any in excess of those required may be inoperative or missing provided:

(a)         The inoperative hand fire extinguisher is removed from the aircraft and its installed location is placarded inoperative; or it is removed from the installed location, secured out of sight, and the hand fire extinguisher and its installed location are placarded inoperative,

(b)         Required distribution of operative units is maintained throughout the aircraft, and

(c)         Procedures are established and used to alert crew members of inoperative or missing equipment.

 

 

 

 

 

Procedures

(M) To provide instructions to placard the inoperative hand fire extinguisher and its location and to secure hand fire extinguisher in an out of sight location.

(O) To provide procedures to inform crew members.

 

Additional considerations:

When determining the location for storage of the inoperative units, compliance with the dangerous goods requirements must be considered.

Additional considerations:

The lavatory smoke detection system is not considered as an acceptable alternate means to the waste receptacle fire-extinguishing system. However, additional relief may be considered if adequate fire containment capability of the waste receptacle can be demonstrated.

Relief provided under 26-25-1B is applicable only if the installation of lavatory waste receptacle fire-extinguishing system is not required by the type certification basis.
