Consider the Role of a Vendor Survey within an EASA Compliant Part 145 Aviation Store

There are several ways we can assess the integrity of a Vendor/Supplier to improve the supplier performance.

Understanding the purpose of Receipt Discrepancy Processes and Component Reliability Assessment including warranty issues.

Why would we carry out a Vendor Survey?

Essentially it is a process that sits alongside the Supplier Evaluation Procedures and enables an ongoing assessment of the effectiveness of the supply chain arrangement with a given vendor.

What do we want to know concerning our vendors?

We want to know how effective is the product that is received from a particular supplier, and we measure this in several ways:

1/ The first way is to generate a receipt discrepancy report (RDR)

If there are any anomalies during the receipt process, we allocate a scoring system that takes into account the number of issues, the size of the issue, and the amount of business we are doing in terms of quantity and value.

In this way, we apply a “weighting” which allows us to identify poor-performing suppliers, so we can take additional quality assurance actions.

2/ Failed on Fit / Bad from Stock

The term failed on fit is used when a new component directly from Stores fails immediately when it is fitted on the aircraft – whilst this part is typically covered by warranty it is nevertheless an unwelcome disruption and all such events incur costs for the organisation.

Often such data as failed on fit/bad from stock does not appear as data within the reliability program so it is necessary to catch this information in other ways – typically by generating a failed on fit document which will act as an initiator for several actions.

Depending on the value of the failure the following may be considered:

a) Quality Investigation as to the reason for the issue

b) Review of Previous audits/events and re-assessment of the vendor audit which was last carried out

3/ Poor Performance in Services

Components once fitted to the aircraft are expected to perform for many thousands of hours – however, when a component fails it is identified and considered in the context of the aircraft reliability system. Communication between the Reliability Department – and the Purchasing Department can identify the Vendor as opposed to Original Equipment Manufacturer (OEM) Issues.

Essentially the objective is to ensure that we have the strongest and most effective Supplier Vendor relationships and we can maintain the best cost controls.
