  A light stop, with an R-parity-violating coupling $\lambda'_{131}$, has been
suggested as an explanation of the excess in high-$Q^2$ neutral current events
observed at the HERA collider. We show that in this scheme a corresponding
excess in charged current events --- such as that reported by the H1
Collaboration --- can appear naturally, without calling for the presence of
light sleptons or additional R-parity-violating couplings, if there exists a
chargino lighter than the stop. The predicted event shapes agree well with the
data. The relevant region of parameter space is identified, taking into account
constraints coming from precision electroweak measurements, atomic parity
violation and recent searches for first-generation leptoquarks at the Tevatron
collider.
