In the OEB 11, the trigger is F\/CTL PART(MOST) SPLRS FAULT ECAM alert. However, some other cases can cause spoilers inoperative, such as:<\/p>\n

Will the cases above also trigger F\/CTL PART(MOST) SPLRS FAULT ECAM alert? If not, should crew apply OEB 11?<\/p>\n

Airbus has not listed all failures leading to triggering the alerts F\/CTL PART(MOST) SPLRS FAULT ECAM. However, independently of the failures, we confirm that the OEB 11 is specific to the case where either F\/CTL PART SPLRS FAULT or F\/CTL MOST SPLRS FAULT alert is triggered.<\/p>\n
For CSC information, the procedure of OEB 11 is to use FLAP 3 for landing because, when the alert is triggered and FLAPS FULL is selected, the flap retraction is inhibited. In the case that PART SPLRS or MOST SPLRS is listed only as INOP SYS<\/strong>, there is no flap retraction inhibition<\/strong>. Therefore, there is no need to apply the procedure of OEB 11.<\/strong><\/p>\n
In addition, note that OEB 11 will be canceled with the embodiment of the FWS S7\/4.0 as indicated in the FOT 999.0077\/22 Rev 02.<\/p>\n
<\/p>\n
Q2:<\/strong><\/p>\n
Thanks for the explanation. That means there’re 2 types of spoilers fault, type 1 is which can trigger the F\/CTL PART(MOST) SPLRS FAULT ECAM alert, and type 2 is which can not. And only type 1 will inhibit the flap retraction. So actually what is the difference between those 2 types?<\/p>\n
However, the trigger condition of F\/CTL PART(MOST) SPLRS FAULT is
\n– PART SPLRs: Between one and eight spoilers are failed.
\n– MOST SPLRs: More than eight spoilers are failed.<\/p>\nAccording to the trigger condition, once only 1 spoiler failed, the alert will be triggerd, without any info about types of fault.<\/p>\n
<\/p>\n

After having carefully reviewed your query, please find below our answer.<\/p>\n
With regards to CSC question, there exist two different cases:<\/p>\n
Case 1: Failures where PART (MOST) SPLRs are listed as INOP items on the STATUS page.<\/p>\n
The display of these items are triggered by other failures and come from other sources. In particular, as shown in image 2 sent by CSC in message \/001, the loss of PRIM 1 + SEC 1 (which may be caused by ATA24 Failure for instance).<\/p>\n
There is no flap retraction inhibition<\/strong> in flight. In these cases, even if PART (MOST) SPLRs are listed as INOP SYS<\/strong>, the maximum downward commanded droop is always high enough for the flaps to push back the spoilers without structural damage<\/strong>. As a consequence, OEB 11 is not applicable<\/strong>.<\/p>\n
Case 2: Failures that lead to F\/CTL PART(MOST) SPLRs FAULT alert in flight.<\/p>\n
In these cases, having PART (MOST) SPLRs inoperative is the main source of the F\/CTL PART(MOST) SPLRs FAULT alert triggering. When the alert is triggered and FLAPS FULL is selected, the flap retraction is inhibited.<\/strong><\/p>\n
We confirm that the recommendation provided in the FOT 999.0077\/22 is specific to the case where either the F\/CTL PART SPLRs FAULT or F\/CTL MOST SPLRs FAULT alert has been triggered<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"
