Description:	A search for heavy neutral lepton (N) production in π + →e + N in-flight decays using data collected by the NA62 experiment at CERN in 2017–2024 is reported. Upper limits for the extended neutrino mixing matrix element \|U e4 \| 2 are established at the level of 10 −8 for heavy neutral leptons with mass in the range 95–126 MeV/c 2 and lifetime exceeding 50 ns.
