We consider the semiparametric accelerated failure time (AFT) model with multiple covariates measured with error. Existing methods for the AFT model are either inconsistent, computationally intensive, or require stringent assumptions. To overcome these limitations, we develop a correction approach for a general smooth function of error‐contaminated variables. We apply this method to the smoothed rank‐based score function for the AFT model. The estimator is consistent and asymptotically normal. The finite‐sample performance of the method is assessed by simulation studies. The approach is illustrated by application to data from an HIV clinical trial.
