  • Publication number: 20240262532
    Abstract: A method manages aircraft parts. A determination is made as to whether a no fault found parameter for a part type is greater than a no fault found threshold for an acceptable level for no fault found occurrences for the part type. The no fault found parameter is how often a no fault found for the part type occurs relative to how often that the part type has been removed and replaced. A determination is made as to whether an average fix time parameter is greater than a fix time threshold for a correct part replacement. The average fix time parameter identifies an average amount of time before a replaced part for the part type was replaced again. An alert is generated in response to the no fault found parameter being greater than the no fault found threshold and the average fix time parameter being greater than fix time threshold.

  • Publication number: 20160314628
    Abstract: Methods and maintenance systems for use in analyzing data related to maintenance of at least one vehicle are disclosed. One example method includes retrieving, by a computing device, a plurality of diagnostic entries associated with at least one fault message from a database of diagnostic entries, each diagnostic entry including an identified corrective action and a date on which the identified corrective action was taken; identifying a plurality of groups of diagnostic entries, wherein the diagnostic entries in a group have a same corrective action, and each group has a confidence level associated with its corrective action; and weighting the confidence level for each group based on an age of the plurality of diagnostic entries in the group.

  • Publication number: 20160104125
    Abstract: A method, computing system and computer program product provide additional information relating to maintenance actions to address an issue with a structure. For each maintenance action that has corrected an issue, a first group of structures in which the issue has reoccurred and a second group of structures in which the issue has not reoccurred are identified. The method then determines an actual correction duration value for each of the structures in the first and second groups, generates a correction duration estimate for the structures in the first group using the actual correction duration values and uses the correction duration estimate to identify a portion of the structures in the second group. The method also uses the actual correction duration values calculated for the first group and the identified portion of the second group to generate a fix duration estimate representing an overall time estimation for issue reoccurrence.
