Recommendations

Assessment Categories and Ratings for Responses to Board Recommendations

Responses to Recommendations are assessed based on the extent to which the underlying safety deficiency has been or is being addressed. The acceptance or understanding of a deficiency is not a criterion for the assessment rating. The assessment criterion is the potential or actual effectiveness of action planned or taken to reduce or eliminate the deficiency.

Four categories are used to assess responses: fully satisfactory, satisfactory intent, satisfactory in part and unsatisfactory.

a) Fully Satisfactory. A Fully Satisfactory rating is assigned if the action taken will substantially reduce or eliminate the safety deficiency. An acceptable alternative course of safety action to the one suggested by the Recommendation may have been taken. The TSB assigns the deficiency file to an Inactive status.

b) Satisfactory Intent. A Satisfactory Intent rating is assigned if the planned action when fully implemented will substantially reduce or eliminate the safety deficiency. However, for the present, the action has not been sufficiently advanced to reduce the risks to transportation safety. The TSB will monitor the progress of the implementation of the planned actions and will re-assess the deficiency on an annual basis or when otherwise warranted. The TSB assigns the deficiency file to an Active status.

c) Satisfactory in Part. A Satisfactory in Part rating is assigned if the planned action or the action taken will reduce but not substantially reduce or eliminate the deficiency. The TSB will follow-up with the respondent as to options that could further mitigate the risks associated with the deficiency. The TSB will re-assess the deficiency on an annual basis or when otherwise warranted. The TSB assigns the deficiency file an Active status.

d) Unsatisfactory. An Unsatisfactory rating is assigned if no action has been taken or proposed that will reduce or eliminate the deficiency. This rating applies to situations where the TSB has received inadequate explanations to convince it that the risks are not worth pursuing. In the Board's view, the safety deficiency will continue to put persons, property or the environment at risk. In such a situation, the TSB should re-assess the statement of the deficiency and pursue the issue with the respondent, in the hope of acquiring additional convincing information. The TSB will re-assess the deficiency on an annual basis or when otherwise warranted. The TSB assigns the deficiency file an Active status.

Deficiency File Status:

If, over time, a reassessment determines that the residual risk associated with the deficiency becomes low, the TSB will assign the deficiency file to an Inactive status.

• Inactive - The assessment determines that the safety deficiency is rectified or the residual risk is relatively low.



• Active - The assessment determines that the residual risk associated with the deficiency is sufficient to warrant continued TSB involvement.
